1. The bra of the future? (safe for work)
2. Findings about paper rejections, or why you should love your critics.
3. Good post on the Dunning-Krueger effect.
4. How penicillin reshaped sexuality.
5. Sabina Knight on Mo Yan (short podcast).
6. How Google lobbies for self-driving cars.
6: So, now we know how Google is going to invest its giant pile of cash: Lobby. #ThereIsNoGreatStagnation
4) is interesting, suggesting that there is a prominent response in sexual behavior compared to costs. Condoms were already widely available that time. I wonder if the effect from AIDS were smaller, and how much of that represented lower relative risk vs. judging a low probability but high negative cost risk.
Similarly, one wonders if there’s any effects in availability of abortion on sexual behavior.
“one wonders if there’s any effects in availability of abortion on sexual behavior.”
you can throw the pill, female economic self-sufficiency, porn and easy divorce into the the mix of cultural changes that have likely had and continue to have an effect on sexual behavior. but this is not new theory for those who read iconoclast blogs.
… or for those who read intro econ textbooks. Duh, supply curves can shift out with technological advances. It is interesting to see how the cultural costs of sex ebbed when the physical costs were overcome by technology, but I don’t think that was the deep point you were trying to make.
I wonder if there is anything to be learned from the different ways that the cultural costs ebbed in different countries? My understanding is that there is basically only a negligible incidence of single motherhood throughout Europe (excluding Great Britain), so I am wondering what is different about the U.S. and Britain from France, Germany, Greece, etc. such that there is such divergence in behavior?
Chinese doesn’t have grammar. Grammar is one of the elements all books are judged by in Indo-European languages. How are Chinese books judged as great when there is no grammar?
Uh, what definition of grammar are you operating under?
Grammar: a system of rules that defines the grammatical structure of a language
Grammar is the structure of a launguage. Are you proposing that there’s no such thing as syntax or morphology in (any of) the (various) Chinese language(s)?
Tauologically speaking, of course.
And I do wonder – do you have any experience with Chinese as a language at all?
Well, no, I don’t wonder at all, actually. But then, just for fun, I’ll point out that Hungarian isn’t an Indo-European language either – where do you stand on its ‘system of rules that defines grammatical structure’.
I was using Ind-European languages as an example. No, Chinese doesn’t have grammar. I just would like to know how works are judged when that is the case.
This is simply not true.
Chinese does not have a grammar? How does one distinguish between “I eat noodles” and “Noodles eat me” then?
I would think that as a Subject-Verb-Object language, like English, Chinese very much has a grammar.
Guys, you’ve all been trolled.
You’re concentrating so hard on the foolishness of the first statement “Chinese does not have grammar.” that you’ve overlooked the complete insanity of the second statement
” Grammar is one of the elements all books are judged by”
Past 4th grade, books are not judged on the quality of the grammar, unless it is so bad as to distract the reader. Even then there is James Joyce.
That paper rejection research is pretty weak- they keep pushing the editors making it better angle but the entire result can be driven by selection of authors who think their paper is worth resubmitting again and again.
That, and/or really interesting work often rejects conventional wisdom, thus being more frequently rejected by peer review.
(2) As @IBES says, there is missing data: what about rejected papers that are not resubmitted? Also: “3–6 years after publication, papers published on their second try are more highly cited on average than first-time papers in the same journal” , well, the findings have been circulating for longer, so more time to get read and cited. Looks like a shoddy paper that makes Editors feel good.
The first link is really uninformative.
– The 5 years survival rates are very deceiving (see: http://youtu.be/4YGqM4nFj7I)
– “In over three clinical trials, the bra correctly identified 92.1 percent of tumors”
And I can detect 100% of the tumours. I just need to assume that all women have got breast cancer! But what about the false positive rate of the BRA? Shall I assume that the positive predictive value of the BRA is very low?
The post is absolutely fantastic! Lots of great information and inspiration both of which we all need! Also like to admire the time and effort you put into your blog and detailed information you offer! I will bookmark your blog!

6. Google spends millions lobbying for a potentially very useful technology? That’s an unfortunate and considerable deadweight loss. Reducing costs in this area might be good for innovation.
it’s a pittance compared to the R&D expenditures to develop the technology, and the downside risk of the technology failing is very high.
Well, yes, that’s true. But it’s still a deadweight loss that could be better spent on R&D and something an engineer developing a tacocopter in her garage may not be able to afford.
Who is this fine lady engineering a tococopter in her garage? Is she cute? (We can assume she’s single).
Dude, your sexism is hanging out.
Yes, and thanks to the nuclear regulatory commission I find I can barely afford to build experimental nuclear reactors in my own garage. Gosh darned government bureaucrats and their stupid safety rules…
I’m not very familliar with US lobbying, but I suspect that the politicians Google is spending money lobbying aren’t actually experts on safety. In fact, I’d even go as far to suspect that the lobbying process might in fact not be wholely concerned with safety and that factors other than just the public interest maybe be involved. So if Google, or other innovators, only had to spend money demonstrating safety, that might be a more efficient thing to do.
Now it’s easy to complain, but you might want to know if I have any practical suggestions on how to improve the situation, and yes I do. I recommend the following three step process, which… Oh my god! My tacocopter is escaping!
2. You mean, your advisor should love your critics.
