anticipate or forerun or what?

[Mmarkotan]

hi, what´s the right way to say if someone speaks about something that is only going to happen as a true fact but someone else disegrees and tells him: let´s not forerun or anticipate or what? What´s the right word to express that someone is making a conclusion too early? I hope I made myself clear. Thanks.

"Assume" is what you are looking for. "Presume" and "prejudge" are even better if you want to come off a bit more critical. "Presuppose" also works. You can caution someone against a rush to judgment or against jumping to conclusions.

You are right. I wanted to put a bit of criticism into such statement. thank you.
