The Let Them Theory Is Wrong: A "Life-Changing Tool" That Millions of People Should Realize is Just Basic Common Sense

A Withering Critique of a Popular Self-Help Guru and What They're Selling (Title and Cover Revised to Meet the Requirements of Specific Online Platforms)

The Let Them Theory by Mel Robbins has been praised across social media as a "life-changing" philosophy, yet one wonders if the buzz is more about clever marketing than meaningful substance. At its core, the book delivers a single, painfully obvious message: you can't control other people—only your reaction to them. This is a truism so well-worn it belongs on the label of a tea bag or at the bottom of an Instagram quote post—not in a book priced as a transformational revelation.

In this critique titled The Let Them Theory Is Wrong: A "Life-Changing Tool" That Millions of People Should Realize is Just Basic Common Sense, scholar Richard Auchter examines and exposes the snake oil and quasi-psychology peddled in Mel Robbins' book, and the influencer industry at large, while also offering pragmatic perspectives on what real personal growth should look like.
