I shared this on my FB page and asked, can ya really blame him?

I was half kidding. I also assumed someone would think of what I did pretty quickly and waiting for the comment to mention what I assumed was obvious.

The timing. I was sure someone else had thought of it.

It's a slow, snowy afternoon. How about a 🧵 on "rationalists" & "rationalism"? I want to talk about what real rationalism might look like & what people devoted to rationalism might actually behave like--and how that differs from what you often see from self-styled rationalists.

Caveat up front: this is not about Slate Star Codex, which I haven't read regularly enough to have an opinion on, or about the recent controversy between SSC & the NYT. I'm more interested in the *idea* of rationalism (vs. the practice).

The core premise of rationalism, as I understand it, is simply that humans' cognitive machinery was not designed by evolution to find truth, but rather to advance the interests & welfare of the collective -- a Venn overlap, but not the same thing. Therefore ...

... reasoning well, both individually & as groups, requires special effort. It requires consciously trying to set aside the parochialism, biases, & other distortions that typically characterize our thinking -- resisting, to some extent, the dynamics of group membership/welfare.

That's all fine. I agree entirely that we should make special effort to reason well & to guard against the typical failures of reasoning to which we humans are prone. I believe it's the best (maybe only) way forward as a species. So far so good.
