The distinction that resolves most of these threads is between what is true on average and what is true for one person.

Same pattern here, and in the same order. The detail I would add is minor and it is already implied above.

Adding the clinical framing, because it changes how the question reads. It is worth asking what the claim would look like if it were false. If nothing would look different, it is not a claim about the world and no amount of discussion will settle it.

Second this. Posting only so the count is not one.

Coming at anna.melb_AU’s question from a different direction. It helps to ask what evidence would change your mind before you look at any. If nothing would, the discussion is not about evidence, and it is better to say so early than to spend nine posts discovering it.

Ask again with the specifics and you will get a better answer than this one.
