Can companies be held responsible for damages from data breaches? If they could, it seems like it would incentivize more caution about what data is collected, and more investment in the security of that data. I also imagine an insurance ind

I was replying to "Inter-Christian conflict is almost nonexistent in 2021". That's a fairly categorical statement, and seems plainly false.

I don't think that's true. Churches are deeply divided on some core issues, and in some cases are splitting over these differences: https://abcnews.go.com/US/wireStory/united-methodist-conserv...

Sure, the article lumps together all kinds of outrage, some of it more serious than others. For example, it also lumps together outrage that someone would commit a micro-aggression like asking "where are you from?" together with

You want to a priori establish some outrage as virtuous and legitimate (ie. critiques around sexism/racism) while dismissing other outrage as silly and trivial (ie. critiques around pressure campaigns to censor culture). Is it possible

This seems to work. The compiler has to see the previous add to know what is in the carry flag. #include <stdint.h> uint64_t addWithCarry(uint64_t x, uint64_t y, uint64_t z) { return x + y + (y + z < y); }

Looks like no type aliases still? Does anyone know if type aliases are anywhere on the road map for Java? Is there some philosophical objection to them?

But "for a given causal model" precisely means "given a set of statements about what causes what." Those statements must be either proved or assumed. If they are already proved, they don't need to be proved further

Do you mean that the new techniques will (1) help you prove which variables should not be controlled for, or that they will (2) help you more clearly describe your causal assumptions, so that you can more easily recognize which variable

by haberman 6y ago
Sure, but what does Pearl bring to the table here? The idea of making falsifiable predictions long predates the "Causal Revolution." The warning of "correlation is not causation" still seems as relevant as ever.
