pchivers··on Children of parents classified as “tiger” have worse grades, are more depressed
I was under the impression that Amy Chua (the woman who wrote "Battle Hymn of the Tiger Mother") gave up the "tiger mom" strategy after one of her children had a breakdown:

"What brings the situation to an end is two horrifying incidents. First, Lulu hacks off her hair with a pair of scissors; then, on a family holiday to Moscow, she and Chua get into a public argument that culminates in Lulu smashing a glass in a cafe, screaming, "I'm not what you want – I'm not Chinese! I don't want to be Chinese. Why can't you get that through your head? I hate the violin. I hate my life. I hate you, and I hate this family!" Her relationship with Lulu in crisis, Chua, finally, thankfully, raises the white flag."

pchivers··on Why Anti-Authoritarians are Diagnosed as Mentally Ill (2012)
This is a great article. The linked article ("Anti-Authoritarians and Schizophrenia: Do Rebels Who Defy Treatment Do Better?") is also very interesting:

"At the 2-year assessment there were no significant differences in severity of psychosis between schizophrenic patients (SZ) on antipsychotic medications and SZ not on any medications. However, starting at the 4.5-year follow-ups and continuing over the next 15 years, the SZ who were not on antipsychotic medications were significantly less psychotic than those on antipsychotics.”

This is exactly what I was looking for. I was previously using http://automation.whatismyip.com/n09230945.asp, but the author is no longer making it available for free.
pchivers··on Feds Seize Barrett Brown’s Legal Defense Fund
I have no idea who Barrett Brown is, but I found this interesting profile of him:

http://www.dmagazine.com/Home/D_Magazine/2011/April/How_Barr...

It seems like he's an Aaron Swartz-like character who is involved with Anonymous.

What percentage of a mortgage payment actually gets converted into equity?

pchivers··on Fired SendGrid Developer Evangelist Adria Richards Speaks Out
"Those who know me well in the the developer and tech community recognize that I have always tried to conduct myself in a way that builds bridges for everyone."

I couldn't get through the first sentence without laughing. How does shaming two men by posting their picture on Twitter qualify as "building bridges for everyone"? I think she is lacking in self-awareness.

pchivers··on Hide your health insurance status and pay cash instead
>A good start, but shopping around is hard, if not impossible

I think shopping around, properly conceived, should be the primary care physician's job. If a doctor is referring e.g. 10 people a month to a specialist, then obviously they are going to be in a much better position to evaluate the options than a patient.

I believe that Sherpaa, Jay Parkinson's company, provides this "shopping around" service (https://sherpaa.com/).

pchivers··on Adderall Addiction: The Last All-Nighter
I didn't like the article either. The whole thing struck me as melodramatic and narcissistic.

Perhaps there are intelligent commentaries to be written about this culture's abuse of Adderall, but this is not one of them.

pchivers··on Bitter Pill: Why Medical Bills Are Killing Us
It's worth noting that there is no relationship between a U.S. hospital bill and the actual cost of the service:

http://truecostofhealthcare.org/hospital_billing

"Hospitals see no problem in sending bills to insurance companies for five to ten times the amount that they actually expect, because they are simply playing the game that the insurance companies fashioned. But remember, they only produce one kind of bill, and it’s designed to send to someone who holds all the cards (an insurance company), and so can just refuse to pay anything they don’t want to pay. That’s their game. But what happens when you have to play the game with the hospital alone (if you don’t have insurance, or if your insurance doesn’t cover that stay for some reason). Then you’re on the hook for the ENTIRE amount. Most hospitals have a policy that allows people to negotiate for a lower amount, but most people don’t know this. And don’t expect the hospital to tell you about it, let alone help out. So even if you can remember to negotiate while you’re convalescing from a long hospital stay, good luck trying to get the deal the insurance company gets.

For the average person, this is no small matter. In the first case, a two day hospitalization that the insurance company got for $2,100 (after the insurance adjustment), would cost an uninsured person over $21,000. The adjusted charge ($2,100) would be a pretty nasty kick in the finances for most families, but they could bounce back. The unadjusted charge, which is what you’ll get if you don’t have insurance, is an almost certain trip to bankruptcy."

pchivers··on Mass shooting at Sandy Hook Elementary School in Newtown, Connecticut
Here is an interesting infographic from the National Post:

http://news.nationalpost.com/2012/07/28/guns-ownership-aroun...

"In 2007, the U.S. had the highest gun ownership rate in the world - an average of 88 per 100 people. But the U.S. does not have the worst firearm murder rate - that prize belongs to Honduras, El Salvador and Jamaica. In fact, the U.S. is well down the list with a rate of 2.97 per 100,000 people. Below is a list of countries with available firearm data from 2007 starting with countries where firearms are most common."

pchivers··on Ecstasy for PTSD: Not Ready for Prime Time
True, antidepressants are much slower acting than MDMA, but you're still looking at 80-90% of people in antidepressant trials who can correctly guess which group they're in (due to side effects such as dry mouth, sleep problems, sexual dysfunction, etc.).

Regarding the issue of whether or not it is poor blinding, I guess it is a bit like the tree falling in the forest but nobody is around to hear it: if you conduct a placebo-controlled study, but all the participants can correctly guess which group they're in, is it really a placebo-controlled study?

pchivers··on Ecstasy for PTSD: Not Ready for Prime Time
From what I understand this 95% figure is not that far off from what is obtained in anti-depressant trials, but somehow the poor blinding of anti-depressant trials is almost never mentioned as a serious methodological problem.

This is discussed in more detail in Irving Kirsch's The Emperor's New Drugs.

pchivers··on Meet the Most Indebted Man in the World
Takeaway quote from the article:

"If you were to go out and start a meth lab in your house, what's the probability that you would ultimately end up doing jail time? It's going to be a lot higher than if you massively defraud a financial institution. It's an endemic problem within the justice system now."

pchivers··on Is there evidence that drugs can help programmers produce “better” code?
From what I understand there is only one study on the relationship between creativity and LSD:

Psychedelic agents in creative problem-solving: a pilot study. Harman WW, McKim RH, Mogar RE, Fadiman J, Stolaroff MJ. Psychol Rep. 1966 Aug;19(1):211-27.

http://en.wikipedia.org/wiki/Psychedelics_in_problem-solving...

The results suggested that LSD has a positive effect on creative problem solving. I think it is a shame that no follow-up experiments have been conducted.

pchivers··on Do you really want to be making this much money when you're 50?
I'm sure sitting on your ass 8-10 hours a day is a health risk. Maybe not as bad as working in a factory breathing in nasty chemicals all day, or dodging falling trees as a lumberjack, but a health risk nonetheless.

pchivers··on A real fMRI high: My ecstasy brain scan
"Ecstasy" was originally used as a synonym for pure MDMA, before the crackdown on MDMA and its precursors. I have no idea how the term is used these days.
pchivers··on A real fMRI high: My ecstasy brain scan
It's highly unlikely that you were using pure MDMA.

http://news.nationalpost.com/2012/02/05/ecstasy-related-deat...

"Ecstasy is so consistently adulterated that when pure MDMA turns up on the street, it’s likely be to sold on the street under the name MDMA or sometimes “Molly.” Corporal Luc Chicoine, the national co-ordinator for the RCMP’s pharmaceutical and synthetic drug operations, has worked on the street in drug operations for 18 years and said he can’t remember ever seeing pure MDMA."

http://news.nationalpost.com/2012/03/19/deaths-spur-research...

"For a sense of just what might be in a given pill, Hudson points to Ecstasydata.org — a Sacramento-based website listing active ingredients and proportions in mailed-in samples — which has tested thousands of hits of “ecstasy” since 2001.

A growing majority contain no ecstasy at all. Since 2010, 61% of 533 samples tested had no MDMA, with 111 containing the drug, and another 96 some combination of MDMA and other chemicals. Of 27 Canadian samples studied since 2010, 14 active chemicals were discovered, including caffeine, methamphetamine, benzylpiperazine (BZP) and procaine."

pchivers··on H - The surprising truth about heroin and addiction
>If heroin really is "so good," why does it have such a tiny share of the illegal drug market? Marijuana is more than 45 times as popular.

One possible reason is that people are squeamish about needles and uncomfortable consuming drugs intravenously.

pchivers··on Who's the Boss? There Isn't One
I don't know if it's possible to figure out which is the chicken and which is the egg in these cases.

Semco, a Brazilian manufacturing company, has been using a "boss-less" style of management since the 1980s. From what I understand they were not exceptionally successful before they implemented this management style.

pchivers··on Is Psychology About to Come Undone?
Richard Feynman on reproducibility in science:

"When I was at Cornell, I often talked to the people in the psychology department. One of the students told me she wanted to do an experiment that went something like this--it had been found by others that under certain circumstances, X, rats did something, A. She was curious as to whether, if she changed the circumstances to Y, they would still do A. So her proposal was to do the experiment under circumstances Y and see if they still did A.

I explained to her that it was necessary first to repeat in her laboratory the experiment of the other person--to do it under condition X to see if she could also get result A, and then change to Y and see if A changed. Then she would know that the real difference was the thing she thought she had under control.

She was very delighted with this new idea, and went to her professor. And his reply was, no, you cannot do that, because the experiment has already been done and you would be wasting time. This was in about 1947 or so, and it seems to have been the general policy then to not try to repeat psychological experiments, but only to change the conditions and see what happens."
