Picture a Thursday night. You are at a table with people you love, and someone says something you would not have defended a few years ago. Then you hear your own voice say, "Well, that's not exactly what he meant."
Nobody pushed you. Your voice just did it.
Where did that come from?
Rarely from one big decision. Mostly from a staircase of small ones. A share that seemed harmless. A shrug at something that once would have stopped you. A "he's just blunt." Each step was small enough to take without noticing.
Psychologists call this the foot-in-the-door effect. In 1966, Jonathan Freedman and Scott Fraser asked some homeowners to put up a small sign about safe driving. It was a tiny favor, easy to say yes to. Some time later, those homeowners were asked to put a large, ugly sign on their front lawns. People who had said yes to the small sign were far more likely to say yes to the big one than people who were asked cold.
Why? Because a small yes tells a quiet story about you. I'm the kind of person who supports this. After that, the bigger request is no longer a new question. It is a test of whether you are consistent. Saying no would mean the first yes was a mistake.
I spent twenty-five years in addictions work, and I saw this staircase again and again. Hardly anyone reached a hard place in one leap. It was a long run of small agreements, each one easy to defend on its own.
In Reversing the Drift, I call the other half of this escalating commitment. The more you have defended a position, the harder it is to change, because changing now means questioning every earlier defense. The foot-in-the-door effect is how the staircase gets built. Escalating commitment is why it feels so hard to walk down.
Two things are worth holding onto.
First, this is ordinary human machinery. It is not a flaw in your character. "You don't drift because you're weak. You drift because you were reaching for something human." If it happened to you, you're not stupid. You're human.
Second, the way back is also a staircase. You do not have to confess the whole thing tonight. You can take one small, honest step. Check one claim before you repeat it. Let one doubt stay in the room. Say out loud, "I'm not sure about that one." A small honest no can do for the way back what a small yes did on the way in.
So here is a gentle question. Not what is the biggest thing you ever defended. What was the first small yes?
Curiosity is a quiet act of courage. You can start there.
