More people should embrace "probably" instead of certainitly.
I recently had someone express nearby me that ADHD is certainly not real, and my immediate reaction was to say, they were certainly wrong. I didn't actually express this because they weren't talking to me.
And upon reflection that reaction itself is wrong. Understandable, but wrong.
They are almost certainly wrong based on current evidence. That is a better framing.
Also for the record, this is what introspection looks like. 😉
