Figure out what you think before you read the comments. After that, it gets harder to tell.

Reading other people’s reactions first does not add to your opinion, it replaces it. Once you have seen the popular take and the clever reply underneath it, your own response gets tangled with theirs and you cannot separate out which part started with you. It happens fast and quietly, with no feeling of being persuaded. You just end up agreeing with the room and calling it thinking.

With the next thing you watch or read, close the page before the reactions load and put your take in a note. Then go look. Comparing the two shows how much of you was in there.
