> Some other poster posted that they must have a pretty specific definition of nudge, because it defies credulity that defaults don’t change outcome if only because half the time I don’t read the defaults or know where to find them.

My pet theory is, these results hinge on, “does it scale?”

Like, yes, you can do nudges and see behavioral changes. But what about when everyone is doing it constantly? Then people will get fatigued and form countermeasures.

Imagine this dynamic in another context:

“Guys, guys check this out, people are guaranteed to buy your product if you show arguments for it to random people!”

But, oops, centuries of marketing later, advertising isn’t automatically effective enough to cover its costs, people don’t automatically believe the ads.
