The Forer Effect is the observation that individuals will give high accuracy ratings to descriptions of their personality that supposedly are tailored specifically for them, but are in fact vague and general enough to apply to a wide range of people."
The Forer Effect is for stupid people. Sure, lots of things are general enough to give the impression of certain things being tailored to the specific circumstances of people who observe them, but if you use your brain, you can tell whether or not most of those things are actually things that can be shared by other people generally and when they aren't. If I have a cousin named, and let's just use a very common name here to avoid any identity issues, "David", yeah, anyone in general could also have a cousin with the very same name. But let's say then that there are some general descriptions of "David" known only to me. THOSE THINGS are NOT shared by others and are generally specific only to ME. If I encounter certain information which describes those sorts of things known ONLY TO ME, then THAT is NOT the Forer Effect.
Still, on this and other forums, I have come across pictures of high school aquaintances, certain family members and even artwork which is SPECIFIC TO ME and I have certainly read a lot of very disturbing descriptions of activities and conversations that have ACTUALLY taken place in my OWN LIFE. How this information is being broadcast in this way, I really don't know, but it isn't the Forer Effect - it's information that is NOT SHARED by other people in general.
Still, BECAUSE I don't understand exactly how it happens, I tend to TRY to IGNORE it in a general sense and chalk it up to the Forer Effect even though I DO KNOW there is something going on other that that.
Finally I will say that noticing things which you people here would call the Forer Effect is what actually keeps me quite sane. It's the dichotomy. Noticing and paying attention to hard phenomena vs a general tendency to see things in soft shades of black and white seems to chase away certain fears and vulnerabilities that have plagued me my entire life.
So, Forer Effect or not, it doesn't matter when the result a small measure of sanity.
