This is the avant-garde preprint service (hosted on AT Protocol) that I've been dreaming of.
If it's a small fraction of its vision down the road, I'd still be happy.

Attention checks are a routine tool used to enhance data quality in online studies. However, a causal inference perspective suggests using this tool with “extreme” care.
