I’ve dumped more than my fair share of truly great guys in my short lifetime. My friends would always say, “He worships the ground you walk on AND he’s gorgeous! Why would you do that?!” My response would always be about how I thought that I liked him, but now that I have him hooked I don’t want him.
In reality, however, it was because they (whomever I was dating at the time) didn’t verify my self-concepts (an individual’s overall beliefs about his or her own personal characteristics). This idea that we all want confirmation of our self-concepts from others is called self-verification (Swann, Hixon, & de la Ronde, 1992). Interestingly, we want this confirmation even if it is negative.
To better explain, I’ll tell you about Mickey (because – let’s face it – I just like talking about boys).

Mickey was such a sweetheart. He sang me songs, made me cupcakes, hung onto my every word. He also showered me with praise, insisting that everything I did was perfect. Normally, one would think this was a good thing, that I should want to date someone who thinks very highly of me. The problem was: I don’t think very highly of myself (at least not on certain traits).
When he would praise me for my singing abilities (of which I have absolutely NONE) or insisted that my looks were goddess-like (again, a clear exaggeration), it would contradict my own beliefs about myself.
There are two reasons such discrepancies are unsettling. The first is intrapersonal; it suggests that I don’t know myself. It’s frightening to think that a person could not know something about themselves; if we don’t then we can’t predict or control things about our own lives. The second reason is interpersonal; it suggests that Mickey had completely unrealistic expectations of my abilities, or that he didn’t actually know me.
Not only do we prefer, remember, and spend more time paying attention to others’ perceptions that are consistent with our own, we intentionally choose to interact with people who corroborate our self-concepts (Swann et al., 1992). This has been shown in everyone from roommates to spouses. In my case, it’s boyfriends.
If my own appraisal of myself were higher, Mickey (and several other all too nice guys) might have confirmed rather than contradicted my self-concepts and we might have lasted longer. Nevertheless, it makes more sense why things work so well with the current beau; he doesn’t even try to stifle his laughter when I sing. He’s smart enough to know when to massage my ego and when to tell the truth.
