Who is we? Of mice and men in longevity science | Book Reviews
The re-election of Donald Trump to the US presidency this year has brought focus on pseudoscience in healthcare and the search for ‘silver bullets’ in health and longevity research. Jason Fletcher …

I wrote a joint book review on three longevity books, posted here. I viewed each book as a different bait-and-switch move. What do you think--do we have any silver bullets for longevity right now?

In 2018, Eric Turkheimer took a bet with Charles Murray, who said that by 2025, the genetics of intelligence would be basically understood. Turkheimer knew otherwise. “I am here to declare that I was more right,” Turkheimer writes.
Your Genes Are Simply Not Enough to Explain How Smart You Are
Seven years ago, I took a bet with Charles Murray about whether we’d basically understand the genetics of intelligence by now.

This whole thread is great, but I particularly appreciate this idea of a “ladder” of research questions implied by a broader theory (and we should be very clear about which question we are attempting to answer in a given paper)
A key idea we develop: *causal theories* can imply *descriptive research questions*.
Consider a simple theory: A -> B. Given these two theoretically relevant objects (A and B), we can articulate numerous research questions.
We build a "ladder" of research questions, some causal, some descriptive.

Any type of cost that is included in the indirect cost rate calculation is disallowed as a direct cost.
If your school charges you rent on space, you cannot add this rent as a direct cost. It is assumed that the government is already reimbursing the school for this.

I've seen a lot of discussions about moving IDC to DC as new categories. Could you explain why this would be specifically disallowed?
