To be clear, I wasn’t talking about during a presentation. I was thinking after, for example on Twitter or in a magazine editorial. The one place I’d be more OK with it is in another paper. But even then if the criticism is rather scathing, I think there is a courtesy to them reaching out and saying — “we’re planning on showing how your method was wrong and your results misleading for this reason in our forthcoming paper”. Because once the argument goes public people tend to dig in their heels and true progress is not likely to be made.
