> The marshmallow test is not really testing hunger or self control. It tests how willing people are to align with authority/the bigger picture.

I feel you're making the exact same mistake as the original researchers.

The marshmallow test is a proxy, but it's impossible to say what it's a proxy for in any given individual. One kid will wait because they're scared the researcher will be angry if they don't. Another kid will wait because they recently learned what marshmallows are, and they actually really want to eat two. A third will not wait, because they've never seen a marshmallow before and would rather try one first before getting two.
