Since I was referenced by name in this thread, I feel obliged to respond. Sorry for missing it until now (you could have linked to it in the original thread; I’d have been here much quicker). This post will also be more of a Great Debates nature.
I cannot present any evidence or studies, but I’m not the one making the claim. What I am seeing is a rather loose claim with no evidence or studies backing it up. Of course, it’s all about definitions: at what point does something become a “trait” that you can test for rather than a normal variation, like, say my love for raspberries?
The self-test, however, is incredibly loaded. Just going through the test and checking the questions that virtually anybody would check got me fifteen. A score of fourteen or higher means you probably have the trait. Even a lower score, if you feel particularly strong about certain of the questions, can mean you have the trait.
Now, of course there are some people who are more sensitive (however you define it) than others. But this doesn’t mean anything like the Highly Sensitive Person trait exists. If it does, and if the self-test is good at identifying it, the ratio is vastly higher than the 15-20% ratio cited on the website.
Now to your cite. I’ll go through it point by point.
“It’s Nothing New” - well, it isn’t, but that has nothing to do with anything, so I’ll let this one be.
“It’s Just Another Self-Help Book (That Is, Just Written To Make Money)” - yep, that sums up my position. She has a website designed precisely to sell the books, including a very loaded test to make sure anybody who takes it will want to buy the books. She claims to base her books on “strong research”, but where is it? I can’t find it on the site (please point it out if it is there). I’d like to know what kind of studies she made, the methodology, the number of subjects, things like that.
“Speaking To Medical Professionals” - not much to say here. It’s all based on accepting the existence of the trait in the first place.
“What About Psychologists and Psychotherapists?” - see above.
“What About the “Hard Core” Scientist?” - haven’t read the articles, so cannot comment. Would like to read them, though.
In short, I can’t see the strong research and hard science she claims is there, and the nature of the site and the self-test doesn’t increase her credibility.
For reference, these are the fifteen questions that I think anyone would check. Note that there are several others I could well have checked, but I erred on the side of caution.
I seem to be aware of subtleties in my environment.
Other people’s moods affect me.
I have a rich,complex inner life.
I am made uncomfortable by loud noises.
I am deeply moved by the arts or music.
I get rattled when I have a lot to do in a short amount of time.
I am annoyed when people try to get me to do too many things at once.
I try hard to avoid making mistakes or forgetting things.
I become unpleasantly aroused when a lot is going on around me.
Being very hungry creates a strong reaction in me,disrupting my concentration or mood.
Changes in my life shake me up.
I notice and enjoy delicate or fine scents, tastes, sounds, works of art.
I find it unpleasant to have a lot going on at once.
I am bothered by intense stimuli, like loud noises or chaotic scenes.
When I must compete or be observed while performing a task, I become so nervous or shaky that I do much worse than I would otherwise.
