Parents Are Junkies
If parenthood sucks, why do we love it? Because we're addicted.
8:00 a.m.: Gas needle points to "empty," but I keep driving to get Rachel to school on time. Car stalls in major intersection. Drivers curse me. I discover I left my cell phone at home. I bang my head repeatedly on steering wheel.
And so on.
And yet. Let's go back to the sofa and that cuddle and kiss. It was a fleeting moment, but it genuinely changed how I felt about the day.
It was at that moment of bliss that I realized how the objective parenting research and the subjective parenting experience could both be right. Parenting is a grind, and most parents are stressed out much more than they are happy. But when parents think about parenting, they don't remember the background stress. They remember the cuddle and the kiss. Parenting is a series of intensely high highs, followed by long periods of frustration and stress, during which you go to great lengths to find your way back to that sofa and that kiss.
We have a name for people who pursue rare moments of bliss at the expense of their wallets and their social and professional relationships: addicts.
Children regularly give parents the kind of highs that only narcotics can rival. The unpredictability of those moments of bliss is an important factor in their addictiveness. If you give animals a predictable reward—say, a shot of sugar every time they press a lever—you can get them to press that lever quite regularly. But if you want irrational and addictive behavior, you make the reward unpredictable. Pressing the lever produces sugar, but only once every 10 tries. Sometimes, the animal might have to go 20 or 30 tries without a reward. Sometimes it gets a big jolt of sugar three tries in a row. If you train an animal to work for an unexpected reward, you can get it to work harder and longer than if you train it to work for a predictable reward.
We've all seen those sad people sitting at slot machines in a casino, methodically feeding coin after coin into the slots. If you made their reward predictable—after precisely every 20 attempts, they would always get a prize—you would lower the addictive power of slots. It's the unpredictability that drives them. Or, to put it another way, it's the hope for reward, not the reward itself, that drives them.
I suspect oxytocin works the same way. The unexpected, kind, and loving things that children do produce chemical surges in their parents' brains like the rush of the pipe or the needle. Like addicts, parents will sacrifice anything for the glimpses of heaven that their offspring periodically provide.
I don't know if there is empirical evidence to back me up, but it's conceivable that the neurological mechanisms of addiction—in all their irrational and self-defeating pathologies—are based on underlying mechanisms in the hidden brain that are designed by natural selection to make us seek out—and enjoy—parenthood.
