It was kind of an interesting take on the subject. But I’m not really sure what upset him so much. I think most people get that psych research is not about them individually. That being said, if something works out for a significant group of people and it’s not going to do any harm to try it, why not?
I write about psychological studies online a lot having been a therapist in the past. I over-rely on the word “suggests” as in "The study suggests that… " and I think in that way it pretty much says that the study is not absolute and conclusive for everyone and sometimes at all. What’s the point of the psychological research if it doesn’t give us some possibilities to ponder and some population tendencies to consider? Is that reserved only for shrinks? I tend to like my research open-sourced. If it works for some people, why not give it a try - understanding that we are individuals and it may not bring the same results for us. In my experience, therapists offer such choices all the time.
The writer himself admits that the suggestions from the blog he cited were pretty good ones. So, his point is correct, but I’m not sure why it had to be made. What’s the harm of exploring the things that research “suggests” for us?
