Dangerous Instincts is a new book by an FBI profiler. It’s all about how to suss out creepy people who have learned not to seem creepy.
Now, after meeting these kinds of people and finding out they’re creeps, you might be able to suss out other creepy people of the same type. But honestly, that’s the kind of experiential knowledge you can do without. (At best, you waste your time and energy on jerks, and at worst, you don’t get to have more experiences in this life.) Also, your psychological makeup may give you issues that cause you to ignore stuff that would be a red flag for other people.
But mostly, for everyday safety, you really ought to use your noggin and your eyes and ears, instead of waiting on your gut to give you emergency warnings. Especially if you have kids, or other people you need to watch over.
So if you don’t want to be working next to Ted Bundy all day while thinking he’s a nice guy, just because he’s never been mean to you (like the crime writer Ann Rule once did), this sounds like a good book to find at the library and stomp into your head, or to buy and keep handy. (I’m being cheap until I find a job, so probably the library for me.)
Here’s another book that sounds similarly useful — In Sheep’s Clothing: Understanding and Dealing with Manipulative People. Just because they’re not psychos, that doesn’t mean you need to put up with it.
