Eight Times Opinion columnists revisit their incorrect predictions and bad advice — and reflect on why they changed their minds.

In our age of hyperpartisanship and polarization, when social media echo chambers incentivize digging in and doubling down, it’s not easy to admit you got something wrong. But here at Times Opinion, we still hold on to the idea that good-faith intellectual debate is possible, that we should all be able to rethink our positions on issues, from the most serious to the most trivial. It’s not necessarily easy for Times Opinion columnists to engage in public self-reproach, but we hope that in doing so, they can be models of how valuable it can be to admit when you get things wrong.
