There are plenty of things we evolved to do/believe/think/perceive that are now harmful, because the world has changed and we haven't yet genetically evolved to fully adapt to it yet (and, because of medical technology, we may never do so). There are hundreds of cognitive biases that exist because they were an evolutionary benefit, but no longer are, or are no longer enough. Predicting how people feel is empathy, and that's great! But stopping there and assuming your predictions are correct without actually verifying them with the person first? That's harmful. You're not too busy anymore running from lions and hunting deer to stop and talk to a person before forming your ideas about them.
