3 Reasons It’s Irrational to Demand ‘Rationalism’ in Social Justice Activism

The scenario is always the same: I say we should  abolish prisons,  police, and the  American settler state— someone tells me I’m irrational. I say we need  decolonization of the land — someone tells me I’m not being realistic.... When those who are the loudest, the most disruptive — the ones who want to destroy America and all of the oppression it has brought into the world — are being silenced even by others in social justice groups, that is unacceptable.

(The link from "decolonization" is to "Decolonization is not a metaphor", to make it clear s/he means actually giving the land back to the Native Americans.)

I regularly see people who describe how social justice activists act accused of setting up a straw man.  This article show that the bias of some SJWs against reason is impossible to strawman.  The author argues at length that rationality is bad, and that justice arguments shouldn't be rational or be defended rationally.  Ze is, or was, confused about what "rationality" means, but clearly now means it to include reason-based argumentation.

This isn't just some wacko's blog; it was chosen as the headline article for the website.  I had to click around to a few other articles to make sure it wasn't a parody site.

But it isn't just a sign of how irrational the social justice movement is—it has clues to how it got that way.

In 2004, The United States government executed Cameron Todd Willingham via lethal injection for the crime of murdering his young children by setting fire to his house. 

In 2009, David Grann wrote an extended examination of the evidence in the Willingham case for The New Yorker, which has called into question Willingham's guilt. One of the prosecutors in the Willingham case, John Jackson, wrote a response summarizing the evidence from his current perspective. I am not summarizing the evidence here so as to not give the impression of selectively choosing the evidence.

A prior probability estimate for Willingham's guilt (certainly not a close to optimal prior probability) is the probability that a fire resulting in the fatalities of children was intentionally set. The US Fire Administration puts this probability at 13%. The prior probability could be made more accurate by breaking down that 13% of intentionally set fires into different demographic sets, or looking at correlations with other things such as life insurance data.

My question for Less Wrong: Just how innocent is Cameron Todd Willingham? Intuitively, it seems to me that the evidence for Willingham's innocence is of higher magnitude than the evidence for Amanda Knox's innocence. But the prior probability of Willingham being guilty given his children died in a fire in his home is higher than the probability that Amanda Knox committed murder given that a murder occurred in Knox's house.

Challenge question: What does an idealized form of Bayesian Justice look like? I suspect as a start that it would result in a smaller percentage of defendants being found guilty at trial. This article has some examples of the failures to apply Bayesian statistics in existing justice systems.
