Agree with this comment but follow up to this tip:

Only use this as a learning technique. Do not accidentally let this bleed over into personal 1:1 conversations.

I know some people in my life who are "smart" and they will cut people off in the middle of conversation to the effect of "oh yeah I already know what you are going to say, let me go ahead and cut you off so I can respond faster".

On top of being completely obnoxious on the face of it, they are wrong enough times in their predictions to where it completely fucks the conversation.
