Yep, In many caste-esque societies, having a darker tone is a sign of having to work outside, thus of lower class. This happens a lot in the Philippines, for example. With a ton of skin lightening products.

Being chubby and pale was desirable when the poor had to toil away outside and didn't have enough food to eat. Being thin and tan is desirable today when the poor have to toil away in offices and don't have enough free time to go to the gym or take vacations in warm places.

Chubby and tan signifies strength and wealth. Thin and pale yet rich is a contradiction, adds mystique and suggests power.

Could be a signaling behavior to encourage spring births. Does UVB peak in the middle of the summer? 9 months later is probably the best time to birth a child for that child's success.

The study measures the effect in mice. Mice have a gestational period of a few weeks, so that's probably not it.

Yes, it’s stupid. IRBs today are, on net, more of a detriment to science than a benefit. When they block a stupid voluntary questionnaire for being “unethical”, just imagine how much other useful science is not being done, because of concern lack of ethics of a similar grade.

IRBs look like a net detrement to most studies because they are a mechanism to prevent really bad/unethical experiments in the far tails of distribution. If those extreme studies were to happen at a non suppressed rate we would be asking for IRBs and talking how science can't regulate itself. So IRBs might be effective but they suffer from the prevention paradox.

Would be interesting to see their reject pile.

IRBs are a net negative because really bad/unethical experiments are done with no oversight by private entities. Their only purpose is to keep ethicists employed.

This has got to be one of the worst takes on IRBs I’ve ever heard.

The basic argument here is that rules are ineffective because bad actors ignore them.

- Before IRBs, unethical experiments were done by professors and grad students with disposal to all of the resources they normally have.

- People don’t always know what the ethical implications of their study is, or how it could negatively impact participants.

- The IRBs are not there to stop research. They are there to help people figure out how to conduct research ethically.

Except those “early hominid” lived in Africa, which isn't known to be the place with the harshest winter. And the fact that humans living in temperate climates and humans in tropical areas belong to a single species makes me believe that adaptation to winter wasn't that big of an evolutionary factor.

Now you assume this wouldn't be something that is common for most mammals. In places where there is always sun there is no reason to evolve away people having more sex when there is sunny. Meanwhile here in northern Europe we get markedly more children during March-April. Which of course could be a sociological thing, or depend on something else, but still.

I believe the phenomenon in Scandinavia that more children are born in spring is partly due to families performing economic optimization wrt. timing of kindergarten and parental leave.

That's a very naive view of the expanding bureaucracy which must grow to meet the needs of the expanding bureaucracy.

IRBs don't need to be ran by anyone more competent than a 5 year old to catch the cases you're talking about. What they have metastasis to today is just another part of the administrative industrial complex which has strangled academia.

It is probably birth control in the water supply that are causing birth rate declines.

That has been thoroughly studied and debunked. Just one example of many: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2854760/ Add to this the fact that less than 1% of the estrogen in the water supply is from The Pill.

Yes. I'd be more worried about estrogen in meat.

Could you give some examples of what cases I’m talking about? I’m just dying to see what kind of straw man argument you’ve been building.

The mere presence of IRBs should discourage bad submissions however you are welcome to contact your local review board and ask for their juiciest rejects.

"The questionnaire we used measured romantic passion, rather than physiological/sexual passion, due to institutional review board (IRB) ethical concerns regarding sensitive sexually oriented questions." Curious about this. I understand ethical boards for psychological blind studies and such, but for questionaires?

https://www.cspicenter.com/p/its-time-to-review-the-institut... classic feature creep + bureaucratization (so it's now done by a special class of IRB administrators, not really by peers, etc)

I would normally be a bit skeptical of anything published by CSPI.
