I thinks there's a similar, simpler, explanation:

1) People who say they don't stress 2) People who say they stress but don't believe it's harmful 3) People who say they stress and believe it's harmful

I find the (3) group is the one actually stressing, feeling all the anxiety etc.

The (2) group just talks about feeling stressed, but they just mean that they had lots of responsibilities etc, they didn't suffer actual stress (the mental issues associated with it) like the (3) group.

What do you mean 'I find' ? How do you find ? By observation ?

Stress has unique biochemical pattern that can be measured.

>What do you mean 'I find' ? How do you find ? By observation ?

By the power of thinking. That is, by considering the provided data, and coming up with what looks to be more plausible.

Sure, it might be wrong.

But without that ability, even the best data are useless, because data are nothing without the interpretation part.

>Stress has unique biochemical pattern that can be measured.

That's irrelevant, though, in this case, because they didn't measure those. As the grandparent quotes: "They started asking people, “how much stress have you experienced in the last year?" -- so it's based on self-reporting.
