Been reading about why "spend $X more for free shipping" prompts work so well, and it traces back to Thaler's mental accounting research. People treat a shipping fee and an equivalent product price increase completely differently, even though it's the same money leaving the same account.

A 2007 study on a French clothing retailer found average basket sizes increased substantially once a free shipping threshold was introduced, not because people needed more, but because the fee was coded as a "loss" (Kahneman & Tversky's loss aversion) rather than normal spending.

Made a short breakdown of the mechanism if anyone's curious: https://www.youtube.com/watch?v=51tFJnKKeDM

Anyone know of other documented cases where retailers explicitly tested removing the threshold and measured the effect on average order size? Curious how consistent this finding is across industries.

Been noticing how many subscription cancel flows put a big, friendly "Pause" button right above a tiny, grey "cancel" text link. Same color psychology as a "are you sure?" popup, just reframed to look like a favor instead of an obstacle.

Looked into the research behind why this works (endowment effect, status quo bias, loss aversion) and ended up making a short breakdown of the actual psychology. Posting here because I think this sub would appreciate the mechanism more than the video itself: https://youtu.be/s5124FW5_l4

Curious if anyone's seen variations of this that are even sneakier.
