Anyone who uses this mechanism is a moron. First of all, it’s untested. These widgets came up with a theory and they are selling it in while in Beta.
Second, each organization (and each job) has different demands. From Facebook, you might determine that someone was, let’s say, overly eager to share information – which might be great for a sales associate, but not so good for a legal assistant.
Is there any single metric anywhere that predicts success? At one point they thought higher GPAs predicted success, but then (at least for engineers) it was discovered that middling GPAs turned out to forecast the best employees.
I understand there are some jobs for which IQ tests are good predictors of success. But think that’s a rare exception.
In the meantime if anyone chooses to use this score to pick a winner, then I don’t expect they would do well in either the GPA or IQ testing.
On the other hand, if you lambast your present boss on Facebook, a reasonable potential boss is going to imagine themselves being similarly treated. Not like you need a score to tell you that.
