The useful interpretation is to exercise empathy and put yourself in the mind of the person writing the questionnaire, and ask what definition they are likely using. For example, your therapist doesn't care if you had a random intrusive thought thirty years ago, they care if you presently have actual designs of self-harm. Likewise, in the OP, the person interpreting the security clearance doesn't care if you were accidentally caught up in a silly witch hunt when you were 12.
Practice empathy. Guess at others' intent in order to do your best to give others the information that they want. But then insist that they use plain English in the future and that doing otherwise is wrong.
This pretty well sums up my experience of the HN comments section.
In this case, however, it wasn't semantic. My ex and I were on the same page as to how we were using "think". She was claiming that by our shared definition of think, most people didn't, and we did.
Sometimes figuring out if they're just obsessing because they're worried about a thought, versus actually perseverating over a potentially actionable drive, is really really difficult.
Not saying you have OCD, it's just a whole area that can lead to seriously debilitating problems for some individuals.
I think I'm pretty neurotypical and fall somewhere in the middle, but I can see how a minor change in that "setting" would have a big impact on my behavior.
I remember a period of my life where I was struggling a bit more than normal with anxiety, and my creative / intrusive brain was like "how about you think on the concept of suicide?" to which my brain responded "wow now you're thinking about suicide, you should really seek help".
In reality, it was just an intrusive thought. But the fact that my brain jumped on that thought, and ruminated on it as "if the thought popped into my head, maybe I'm not OK", that was the thing that caused problems.
The effect is similar to the statement, "don't think of a blue elephant" - it's pretty hard to not immediately think of some kind of a blue elephant (Dumbo the Disney character? A wild African elephant that got blue mud all over it? A painted elephant in a Indian potentate's parade? Etc.)
Psychologists use the term 'ideation' to distinguish between merely thinking about a topic, versus obsessing over a topic, making plans related to a topic, and so on.
I don't think that it's some people follow prescribed paths. I think everyone has familiar and less-familiar paths, and some paths are totally out of the way. And I think the overlap of what's considered familiar and what's considered out of the way have much less overlap than is commonly understood.
Thanks.
Seriously though, I suppose I was misusing the word "evidence" here... I haven't actually studied this beyond observing and talking to people I know. I would also be interested in reading on the topic if anyone can suggest something!
