The Mere Exposure Effect says that people get familiar with a message when exposed to it 10-20 times. 😱😱😱
That’s correct. 10-20 times.
You’re the same when people tell you things.
So if you want to get someone else to do, think or feel something, you need to tell them repeatedly and ideally across multiple channels.
Maybe not as many as 10-20 times. But certainly more than once.
