Three Paths Through the Levels of Selection

Have you ever wondered about individual-, group-, and multi-level selection arguments? Packed with strong opinions, vehicles and replicators, the Price equation, and causal graphs, I hope you find some answers in my new paper. Please share widely!

I am frustrated and enraged at the UCP and Danielle Smith, for using the most powerful constitutional hammer we have to vaporize human rights for children and their parents.
I am disgusted by these Conservative MLAs. Every single one of them has taken leave of their senses and their humanity.

Today, Alberta introduced Bill 9 and invoked the notwithstanding clause to shield three anti-trans laws from constitutional challenge. These laws deny gender-affirming care to youth, erase 2SLGBTQI identities from schools, and ban trans girls and women from sports.

This is THE story of US poverty: that scores of people do everything Republicans say they want them to do—hold a steady job, be married, etc—and still be poor. I recommend this paper to anyone willing to understand this: www.science.org/doi/10.1126/...

A Sharon Begley byline, almost 5 years after her death.
Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."
Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.

I guess Rubin choosing "Missing at Random" for the scenario in which it is evident that the data are not missing at random is a close contender.

The Canadian government has seemingly never read a single one of its own commissioned reports on what Canadian science needs. (It's not more people.)
Globe & Mail reports “the budget is expected to include up to $1-billion to attract high-quality talent and researchers from the United States and elsewhere”
So far hospitals and universities have been going it alone….

In a new paper, we show from longitudinal UK and France data that income volatility (fluctatuations month to month) are bad for mental and general health. And it is much badder than you would expect given the lowness of the low months:

How over- and underrepresented are different causes of death in the media?
Another way to visualize this data is to measure how over- or underrepresented each cause is.
To do this, we calculate the ratio between a cause’s share of deaths and its share of news articles.

Sometimes I think about how from 1935-1975ish, Bell Labs produced an insane amount of revolutionary science and technology, including 11 Nobel Prizes, the transistor, UNIX, C, the laser, the solar cell, information theory, etc. The secret? Provide scientists with ample, steady, no-strings funding.

Will be a little sad forever that we got the clearest object lesson possible that each individual's health is inextricably related to every other individual's health in a society, and we seem to have come out of it with even less collective will to reshape our society relative to this knowledge.

That ratio, in turn, is a downstream effect of decades-long defunding of higher education such that institutions cannot afford enough qualified instructors for the student populations that increased for decades as administrations attempted to replace lost funding w tuition dollars

The result is a set of mutually reinforcing trends where fewer, lower-paid instructors buckle under (until recently) a constantly expanding student population. The students themselves caught in another accelerating debt crisis to complete their educations amidst rising costs
