I think this is great. I'd just try to cut the text in half. Here's my attempt:

Double Standard Test:

Do you let your own side's bad behavior slide, or hold everyone to the same standard?

Selective Skeptic Test

Do you question your own side's beliefs as much as you criticize the opposition?

Status Quo Bias Test

If the status quo you're defending was a weird fringe view, would you still fight for it?

Ideological Turing Test

Do you understand your opponent's argument so well that you could pass as one of them?

Conformity Test

If your allies suddenly changed their mind, would that alone make you change your mind?

Outsider Test

If a wise stranger was standing in your shoes, what decisions would they make on your behalf?

It might be worth crossposting this to LessWrong.

Could you share an editable link?

a tiny font attribution I think would be helpful, like

Inspired by "The Scout Mindset "by Julia Galler

so people can find the book on the interwebs.

maybe a short url pointing to the poster (on Canva) can also be in your interest, don't know enough about Canva, though.

I love this! Thanks for sharing :)
