In general, UI changes seem to be rolled out when devs feel like it and decide they look good, and changed in response to vocal feedback.

Will the Manifold team try rolling out a UI change with systematic or quantitative testing, before 2024-04-01?

Things that would count:

• A/B testing the rollout so that only some users get it at first, with some kind of metric tracking.

• Publicly discussing what metrics were tracked around the UI change, and how they were interpreted as good or bad.

• Systematically and intentionally seeking feedback on a proposed or actual change, via a mechanism likely to have significantly less selection bias than "voluntary feedback from users engaged enough to be on Discord".

• Creating a decision market that will resolve based on quantitative metrics and reporting those metrics.

The testing must be public enough that I can find evidence of it in order to count. This question resolves N/A if there are no UI changes whatsoever before close. I wouldn't be surprised if there are weird edge cases; please ask about them. I won't trade in this market.
