Why I Don’t Hire College Graduates

A 1924 magazine article called “ Why I Never Hire Brilliant Men” contains this:

Every year I picked up a half-dozen live young fellows who seemed to have a capacity for hard work, and shoved them in at the bottom of the pile, letting them make their way up to the better air and sunlight at the top — if they had it in them to do it. For a time I tried picking these youngsters out of the colleges. But my experience with college men was not fortunate. If I selected good students, I found too often that their leadership had been won by doing very well what their teachers had laid out for them. They had developed a fine capacity for taking orders, but not much initiative.

The notion of not hiring college grads now seems absurd, perhaps because the fraction of people who go to college has gone way up. But it’s hard to believe that the selection pressures operating within colleges have changed. College professors are still a tiny fraction of the population.

I came across this magazine article randomly browsing but this quote is another way of saying what two of my recent posts — my student’s term project about overcoming stage fright, and about jobbook.org – were about. If most people must spend four years in a place (college) where those in charge (professors) value only a small fraction of their abilities, a lot is lost.

Omega-3 and Dementia

A new study has found that older people with less omega-3 in their blood are more likely to suffer from dementia. The study involved about 1000 persons 65 or older randomly sampled from two Italian towns. They were given mental tests and divided into three groups: no cognitive impairment; cognitive impairment but not demented; and demented. In addition, their blood was measured. Worse mental function was more strongly associated with total omega-3 fatty acids (p = .01) than any of the other fatty acid measures.

One more reason to think that consuming more omega-3 might improve your brain function.

jobbook.org: up and running

jobbook.org, a website to help students choose careers, is up. Aaron Swartz and I have been working on it for several months. We hope that it will eventually contain lots of first-hand information about jobs so that students (and anyone else) can learn what the jobs they are interested in are really like. Aaron has called it an “encyclopedia of jobs.”

To decide what to do, Aaron and I visited several schools around the Bay Area. At San Francisco State, a nursing student said, “I’m a nursing major, but I barely know what nurses do.” When I was in school, I could have said the same thing: By deciding to go to graduate school in experimental psychology I was choosing to become a “professor major” but I knew little about what professors did. Even as a graduate student I barely knew what they did. This reflects a truth about modern life: It is hard to learn what jobs are like. You can do an internship, but schools like UC Berkeley don’t make that easy. And internships take a lot of time. The goal of jobbook.org is to provide the same information much more easily.

jobbook.org is a wiki — a Wikipedia-llke website than anyone can edit. We hope that people on both sides — people with job knowledge and people who want job knowledge — will contribute.

If you have a job (any job!), we hope that you will offer to be interviewed about it. (To make that offer, just add your job, location, and contact info to the home page.) You don’t need to wait to be interviewed: You can simply describe an actual day of your job and add that description to the site.

If you are interested in learning about any job, we hope that you will request an interview. (To make that request, just add the job and your contact info to the home page.)

We hope that these offers and requests will produce interview transcripts that will be added to the site. If you know of a helpful link (such as a book or magazine article), we hope you will add it.

Last night, there was a meeting for interested students in the Channing-Bowditch (a Cal dorm) lounge. I expected no one to show up. Four people did. Next meeting: next Monday (Nov 5), same place, see home page for details.

Sabine Alam, Khoi Lam, and Michelle Nguyen are the Advisory Board who have been giving Aaron and me sage advice. Thanks to them.

My Theory of Human Evolution (early value system)

From a review of The Surgeons: Life and Death in a Top Heart Center by Charles Morris:

For better or for worse, the quality of health care is driven by what Morris calls an “artisanal” value system, one that has little to do with institutional allegiances or administrative management objectives, but rather with “internalized systems of ethics and the expectations of other professionals.”

My theory of human evolution says it started with hobbies. Hobbyists became artisans. It hadn’t occurred to me that an “artisanal” value system exists but what Morris says makes sense. Such a value system should be powerful, easy to spread, and hard to eliminate.

Autism Linked to Mood Disorders

Mood disorders appear to be much more common among the relatives of autistic children than among the relatives of other children. A survey article about this appeared in 2004. Here is a bit of the data:

In North Carolina, between 1988 and 1990, we studied 40 autistic individuals (20 attributable to known neurological disease and 20 idiopathic). Family histories, using the family history method, without knowledge of the neurological status, showed a low incidence of major mood disorder in the neurological patients (only two had family members with major depression, none with bipolar disorder). In the idiopathic autistic patients, by contrast, major depression was found in 14 and bipolar disorder in 8 of twenty families.

Between 1995 and 2002, we acquired another series of patients included in our study of fluoxetine treatment for young autistic spectrum children. We determined family history data as before and sought information about family members with special intellectual abilities or attainments, inspired by observing such individuals in many of the families. The abilities most often were scientific, mathematical, or computational but included others (e.g., professor of philosophy, professional musician). Analysis revealed a strong correlation among three groups: autistic probands responding to fluoxetine, family members with major mood disorder (especially bipolar disorder), and family members with special intellectual abilities. In this study, history of major mood disorder (in first- and second-degree parental relatives) was assessed in 151 families. One hundred and eleven families (74%) had a history of major depression (in 102) and/or bipolar disorder (in 52).

In other words, mood disorders were more common among the relatives of autistic children who responded to fluoxetine (Prozac) than among the relatives of autistic children who did not respond to fluoxetine. I have wondered why autism seems to be increasing. This linkage suggests it may have something to do with the long-term increase in depression.

How Things Begin: The Flynn Effect

The Flynn Effect is the steady improvement in IQ scores over the last 50 years or so in many places. It was documented by James Flynn, a professor of moral and political philosophy at the University of Otago. Flynn gave a talk at Berkeley recently. I asked him how the Flynn Effect came to be.

Flynn finished college at the University of Chicago in one year (lots of advanced placement) and went on to get a Ph.D. at the same school. His first job was at Eastern Kentucky University. It was during the Korean War; better schools were afraid he’d be drafted. He lost that job because of his CORE (Congress for Racial Equality) membership. He got another assistant-professor job at Lake Forest. He lost that job because of his socialist views, although “sins” such as assigning readings beyond the set test were also given. He and his wife decided to go to New Zealand, where his politics would be more acceptable. He got a job at the University of Otago, where he has been ever since.

In the 1980s, he started to write a book defending humane ideals. One > question he wanted to answer was how to combat racism. He came across Arthur Jensen’s work. Jensen’s work was not easily dismissed. It was based on data. To properly answer Jensen, he believed, you needed data — a radical view for a philosophy professor. This was outside his area of training. He asked a professor of psychology for advice. The psychology professor was dismissive; his attitude was “what could you possibly contribute?” But Flynn did not see that psychology professors were substantially smarter than everyone else; the necessary skills should be within his reach, he thought.

He studied the math behind IQ tests for two years. He started looking at data. He looked at IQ test manuals and discovered that the raw scores kept increasing over time. He found six examples. He wrote a paper based on these examples and sent it to the Harvard Educational Review. The editors (who, unknown to Flynn, were graduate students) rejected it. Everyone knows intelligence is going down, one reviewer wrote. This made him mad. He went out and found 14 more examples. With 20 examples, he wrote a paper that was accepted by Psychological Bulletin. The reviewers were stunned, he said, but couldn’t find any holes in his case. It appeared in 1984.

Arthur Jensen pointed out that the tests concerned were heavily influenced by education and predicted that a test like Raven’s would show no gains. Flynn collected data from around the world (14 nations) and found that the largest gains were on Raven’s. The resulting article appeared in Psychological Bulletin in 1987.

Flynn said that only now (in his new book What is Intelligence?) can he give a coherent explanation of the gains.

I Learned that if I Really Wanted To, I Could Conquer My Fear

In an upper-division depression seminar I taught in 2002 the term project assignment was to do whatever you want related to depression so long as it does not involve library research and is off campus. Several students decided to give a talk about depression to a high school class, including Cindy Voong. She wrote this about her experience:

Five years ago, I graduated from Oakland High School, a public high school with a dominant African American and Asian population. A little over a week ago, I revisited my old high school as a guest speaker for Mr. Tinloy’s 3rd period psychology class. It was not as bad as I thought it would be. I was quite nervous and terrified of speaking in front of a classroom full of juniors and seniors, but I made it out alive, and it was a good learning experience.

My friend, a former student of Mr. Tinloy, brought me to his classroom during the break between 2nd and 3rd period, and introduced me. I was pretty nervous. Speaking to teachers and professors always makes my heart beat a little bit faster than normal. I spoke to Mr. Tinloy very briefly. I introduced myself, explained why I was there, and asked him if he would be interested in having me speak to his class about depression. He was very nice. He wanted to know what I planned on talking about, so that he could critique it if necessary. I made arrangements to contact one of the students (I actually knew five of his students, much to my surprise) and get his notes on what they have covered in class so far before I decide what I wanted to talk about. We made a date for when I would come in (April 26), and before then, I was to email him an outline of my talk. That was the first step. Whew!

Shortly after my first meeting with Mr. Tinloy, I contacted Simon, one of his students, and got his notes for the class. After reviewing his notes, which covered articles and brief overviews of what depression is, I emailed Mr. Tinloy a tentative outline of what I might talk about. Now that I look back on it, the list was actually quite long. I don’t know what I could have been thinking about. The outline is as follows: different types of depression, symptoms and signs of depression, treatment (both pharmaceutical and therapeutic), theories on why someone might become depressive (maybe including evolutionary viewpoints), depression in childhood and adolescence, suicide, social stigma (political perspective), and what one can do to help a depressed individual.

Before I emailed Mr. Tinloy, I took out all my psychology books and skimmed over the depression sections of the text. They all pretty much went over the same things, so I thought I would give them a review of what I thought they already know. Mr. Tinloy emailed me back that I should plan on about 20 minutes and that I should talk about whatever I felt most comfortable talking about. I was kind of surprised that he did not give me more feedback on what he thought I should cover, because when I spoke to him the first time, it seemed like he would be more critical about what I would talk about, but he was pretty relaxed and carefree about the whole situation.

When I received his email and read 20 minutes, my first thought was, “Yes! Twenty minutes only! I can talk for 20 minutes!” One of my biggest fears is talking in front of a big group. I was afraid that if I were given more time I wouldn’t know what to say. Then I looked at my outline and thought, “Uh oh! Revision!” I knew that I could not possibly fit in everything in 20 minutes. So I looked over my list, and decided to focus on the evolution of depression. That was a topic I did not see in neither my psychology textbooks nor in Simon’s notes, so I thought something different might be more interesting.

I had originally planned on having overheads, so that all the attention would not be on me, but it was just my luck that Mr. Tinloy did not have an overhead projector. This made my talk even more of a challenge. I was terrified of the idea of standing in front of that classroom and talk for 20 whole minutes. I have given five-minute presentations in class before, and even five minutes was too long for me. I thought I was going to go into that classroom and freeze up. My nerves were definitely working against me.

Mr. Tinloy teaches two psychology classes, 2nd and 3rd period. I was supposed to come in at 9:20 am, the last twenty minutes of 2nd period, and stay for the first 20 minutes of 3rd period. I arrived to the class at 9:25 am, five minutes late. The class was watching a video on autism, schizophrenia, and other psychological disorders. When I entered the classroom, my heart was pumping like crazy. I was so nervous I literally forgot my whole talk. I think Mr. Tinloy sensed how nervous I was, because he asked me if I wanted to start with this class, or if I wanted to wait for the next class. It was up to me. I tried really hard to gather my thoughts and settle my nerves, but I could not. I started to worry that 15 minutes would not be enough time for me to get through everything. Then I worried about what I should and should not talk about with my time limit. The thought of turning off the television, which only half the class was paying attention to, and having their attention turned to me frightened me even more. I was not yet comfortable in the classroom. It was extremely intimidating. I was definitely not ready to speak. I would have only succeeded in making a fool of myself if I decided to speak. So I did what I had to do. I told Mr. Tinloy I will wait for the next class. (Yes, I chickened out!) But I am very glad I decided to wait for the next class. For those 15 minutes, I calmed myself down, and made myself more at home in the classroom. I sat on a high chair in front of the class, getting myself accustomed to being in front of a class. I showed Mr. Tinloy my notes, and he thought that the four evolutionary ideas were interesting. He saw that I had questions I wanted to ask the class, and pointed out that it was really important to engage the students in discussion with questions to keep their interest. So I sat there and reviewed my notes.

When the class ended, and students from 2nd period started to file out as 3rd period started to trickle in, I found it less intimidating to be in the classroom as the students one-by-one came into the classroom than to come into a room filled with students already. My friend, who had introduced me to Mr. Tinloy, was also there to give me some moral support. As the students started to come in, I counted five kids whom I actually knew. At first I thought that it was kind of cool to have them there, and that it would make it less scary. But then it made me a little more nervous, because they were people I knew. What if I gave a totally lame lecture? I would never hear the end of it! So I started to have all these mixed anxieties again.

When class began, Mr. Tinloy introduced me to the class, and the stage was all mine. Thirty or so pairs of eyes looked my way. I smiled, and pretended I was extremely confident, and that I gave talks all the time. I gave them a general definition of depression. The first question I asked them was, “Are you guys familiar with the DSM-IV? Do you guys know what it is?” Gosh, those two seconds of silence was deadly. No response at all. The crowd was dead before I even started! Very, very discouraging! Then someone said, “Yeah.” Mr. Tinloy then told me that they kind of went over that. That was my cue to keep going. I read them the DSM-IV criteria for depression to kind of jog their memory a little. I then introduced the topic of my talk… Why depression?

To get them to start thinking about what I meant by “the evolution of depression” and why there is depression in modern society, I posed them with a few questions from Solomon’s evolution chapter. Why would such an obviously unpleasant and essentially unproductive condition occur in so large a part of the population? What advantages could it ever have served? Could it simply be a defect in humanity? Why was it not selected out a long time ago? Why do particular symptoms tend to cluster? What is the relation between social and biological evolution of the disorder? Why do we have moods at all? Why do we have emotions? What exactly caused nature to select for despair and frustration and irritability, and to select for, relatively speaking, so little joy?

I pretty much read off these questions, and did not realize that I was reading them off too fast to actually allow them time to think about one before I rambled on to the next question. Mr. Tinloy helped me out a bit, and asked that I repeat the first question. So I reread the questions, one at a time, slowly, to allow for discussion if any one questions struck the students at all. Unfortunately, the students were pretty reluctant in participating in discussion. Mr. Tinloy seemed to be the only person interested in what I had to say, and he tried to answer some of the questions I posed, which in itself led me into the next portion of my talk… the four proposed answers to all those questions.

Even though the students were not very responsive, I found myself getting more comfortable talking. Mr. Tinloy was asking questions, and I actually knew the answers! I was so proud of myself for being able to answer his questions with confidence, which made me more confident. I knew more than I thought I knew!

So I went into each of the “proposed answers to the ‘why’”. I would read off one proposal (e.g. Depression served a purpose in evolution’s prehuman times that it no longer serves.), and explain to them what it basically meant, and where such a proposal came from. One thing I feared going into the lecture was that I would be reading off my notes the whole time, and not look at the class, so I decided to go into the classroom with just my outline. I was also afraid that I would freeze up and have nothing to go on if I just had my notes. But I am extremely glad I didn’t have everything all typed up, because it allowed me to talk more freely. It also made me seem like I know my stuff. =)

So after each explanation, I would allow for any questions anybody might have. Mr. Tinloy kept asking me question after question, and I kept answering all his questions. I was really enjoying the talk. It was as if we were having a private intellectual conversation. We touched on a lot of interesting things that I had not intended to talk about, so I was extremely glad I had read all those chapters closely! We talked about things from why more females are depressed than males to medication to positive illusion. It was also during this portion of the talk that a couple of the students were starting to participate, so I was really excited. One of the students asked about medication, and getting off medication, so I was really excited to inform them that the myth that getting better meant getting off medication is not true, and that for most people, staying better meant staying on the medication.

For the last portion of my talk, I had four passages from [Andrew] Solomon’s hope chapter [in The Noonday Demon] that I wanted to read to them, that I thought were very powerful. I wanted to end the lecture on a good note, something they could go home and think about. When I looked at the time, I realized that I had talked too long, and resorted to only reading two of the passages. This portion of the talk seemed to get the most response from the class. I started off asking them what comes to mind when they think about a depressed person. They pretty much gave a similar answer to how Solomon had described it. So I went on to read the first passage:

Psychiatric illness often reveals the dreadful side of someone. It doesn’t really make a whole new person. Sometimes the dreadful side is pathetic and needy and hungry, qualities that are sad but touching; sometimes the dreadful side is brutal and cruel. Illness brings to light the painful realities most people shroud in perfect darkness. Depression exaggerates character. In the long run, I think, it makes good people better; it makes bad people worse. It can destroy one’s sense of proportion and give one paranoid fantasies and a sense of helplessness; but it is also a window into truth.

I was pleased to find that half the class is no longer falling asleep. They were giving what I said some thought. Some actually responded!

The first passage I skipped was about the interaction between illness and personality, and that a sense of humor and love gives hope. The second passage I skipped was the part about how you are your choices.

I ended the lecture with one last passage from Solomon’s hope chapter:

Depression in its worst is the most horrifying loneliness, and from it I learned… So many people have asked what to do for depressed friends and relatives, and my answer is actually simple: blunt their isolation. Do it with cups of tea or with long talks or by sitting in a room nearby and staying silent or in whatever way suits the circumstances, but do that. And do it willingly.

After that, the class clapped, and Mr. Tinloy asked the class if there were any more questions for me. There were a few questions like “What year are you?” and “Are you going to be a psychologist?” but that was it. I was pretty surprised that nobody had any questions about Cal, but I guess those who planned to go to college already know where they are going, and have pretty much become familiar with all the info. When all was done, Mr. Tinloy thanked me for coming, and told me that I did a very good job and that I should come back to visit anytime I wanted.

I walked out of the class with a huge sigh of relief. I was so glad that it was over with. The one thing that surprised me the most was that I kept talking, quite freely, without relying on my notes too much, and for FORTY-FIVE MINUTES! I was also very thankful that Mr. Tinloy was there to guide me through the whole process, and was there to keep the lecture going. I was even more thankful that I was able to answer all the questions he fired at me, because I was afraid I would be unable to answer a question, and the students would look at me and think that I was a flake.

Overall, this was a very difficult, but rewarding experience. I was able to overcome my many fears, and talk! It feels very different being in front of a class, and not in the class, hiding in the crowd, like I tend to do. It did not surprise me much that I got the response I got from the class. Five years ago, I was in their shoes. Guest speakers meant a break from the regular class work, nothing more. Most of them have senioritis, and do not want to do anything anyways. Nevertheless, I went in there hoping for the best. It was very nerve-wracking and intimidating at first, but it was not too bad. I was disappointed that I bored most of them to death, but very glad that I held the interest of Mr. Tinloy and at least two students the whole time. I was also very surprised that the students’ interest rose toward the end of the talk. It actually turned out much better than I thought it would, at least on my part.

I later on asked my friend for her honest opinion about my talk. She said that my presentation was good, and that I didn’t look nervous at all, and that I knew my stuff, but she was fighting to stay awake, because the topic did not interest her one bit. She is a business major, and had no idea what I was talking about. She thought I did a better job that she expected.

I also asked one of the students I knew from the class what she thought. She said pretty much the same thing, that I did a good job, but that it was boring because she wasn’t all that interested in what I was talking about, but it got more interesting toward the end when other students started to talk. “Nobody likes guest speakers, so it’s okay.” I don’t know what to make of that. Is that a good thing or a bad thing?

I have always found high school students a very intimidating group to work with, because they are on the verge of adulthood, yet not quite mature enough. I don’t know if it is because of the high school that I went to, but I find that high school students think they are on top of the world, and that they know everything, so they tend not to listen to adults as much as kids or even other adults would. Students in high school are there because they have to be, so not everyone is there because they want to learn. That is why I have to agree with Solomon when he said that it is easier to talk to a room full of psychologists than it is to talk to a room full of high school kids. With a room full of psychologists, you at least know that they will be interested in hearing what you have to say. This whole experience reconfirms my decision to stick to teaching grade school kids after graduation. Third and fourth graders are more likely to listen to what I have to say, and they are shorter than me. However, seeing Mr. Tinloy interact with his students make it a little less scary to teach in a high school setting. Mr. Tinloy seems to have a very comfortable and close relationship with all his students. It is that bond that he developed with his students that made them respect and listen to him. If ever I was to teach at a high school, I think I would definitely have to adapt Mr. Tinloy’s style of teaching.

Have I changed as a result of this class project? In a way, I have. I learned that if I really wanted to, I could conquer my fear, and do what I have to do. Speaking in front of any kind of crowd has always made my heart pump like there is no tomorrow. Forcing myself to speak in front of a high school class made me realize it’s not as bad as I thought it would be. As long as I can put my fear aside, and carry some confidence, I can talk forever! (Well, you know what I mean.) And the most important part of having that confidence is knowing your stuff! Being able to answer questions is the biggest confidence booster there is. I think I will use this as an example for future reference. I know that this will not be the last time I have to give some sort of presentation in front of a group, and it won’t be the last time that my heart starts racing when I get in front of a crowd, but I will be able to remember this experience, and tell myself, “It’s not that bad.”

I was enormously impressed by this paper. Not only by the pragmatism and courage she had shown, but also by the realization that conventional college assignments, including mine, would never have revealed she had these strengths.

Why Blog? Interview with Janet Ruhl

Janet Ruhl blogs about diabetes and maintains a website called “ How to get your blood sugar under control.” Thanks to Dave Lull, I came across her critique of Good Calories, Bad Calories (”some of the densest writing I’ve encountered in a long life of reading popular science . . . its core message is VERY important” — I agree with both) and noticed a comment by her that blogging turned out to be a good idea. Ah, blogging. She kindly agreed to answer a few questions.

Why did blogging turn out to be a good thing to do?

Blogging introduced me to a new group of younger people who have been a pleasure to interact with. I was accustomed to the more traditional web information exchange venues, having been active in online forums since I joined Compuserve in 1987. But many of the bloggers are younger and don’t appear to be familiar with the newsgroups or even the larger discussion forums dedicated to my topic. Once I started blogging and syndicating my blog [via RSS], these bloggers introduced themselves [by commenting on her blog]. I really like the positive supportive atmosphere that they bring to interaction.

What have you learned from blogging?

In the health community, at least, the younger people whose online communication is confined to blogging seem to be more positive and supportive and less likely to use internet communication to indulge the kinds of flaming and obsessional nuttiness that seems to have destroyed the newsgroups as a viable place for intelligent discourse. They also make very good use of multimedia when making their points.

You seem to be saying blogging brings out a better side of human nature.

Not really. It is just that the structure of blogging allows each person to be heard, and leaves it to the audience to vote with their attention for content. Stridency and conflict are minimized because comments are moderated. A person can, of course, contradict another person, in their own blog, but they have to attract readers and conflict alone is not a strong attraction.

Science in Action: Omega-3 (simple reaction time)

A friend who has known me for years said I became more talkative recently — around the time I started taking flaxseed oil. In the letter-counting task I have been using, there is an increase in error rate at the same time that flaxseed oil is reducing reaction time — I become more “jumpy”. It is as if flaxseed oil lowers a threshold for action.

Maybe I could measure this. Following some of Greg’s principles, I devised what experimental psychologists call a simple reaction time task: I see colored circles on my laptop screen and press a key on the keyboard as quickly as possible when a circle appears. The computer beeps 0-4 times depending on how fast I respond.

With the letter-counting task, I kept improving for at least 100 sessions. With this task, I stopped improving (getting faster) after about 2 sessions. I took 4 T flaxseed oil around 2 pm and measured my reaction time before and after. Here are the results.

flaxseed oil and simple reaction time

My reaction time decreased with roughly the time course I’d seen in other tests. The percentage decrease was unsurprisingly small but it was quite clear. It was hard to tell how long it lasted.

I was impressed how easy the whole thing was. It only took about an hour to write the experiment-running program (because I could modify something I already had) and the necessary pretraining (learning the task) was trivial (a few minutes, in contrast to weeks with the letter-counting task). I’m unsure how much follow-up of this I will do but it was reassuring to find similar results (flaxseed oil improves performance) in another task.
