Love does things to a person -- you know this well if you've been in love, or within a hundred feet of a friend who is. Frilly-collared poets would have you believe that it's all part of love's magical spell, but luckily science has weighed in on the subject to let us know that love triggers all sorts of weird chemical and physical changes inside our brains and bodies. And once you know about these changes, it actually explains a lot ...
5Love Makes Us Go Blind (Figuratively)
We all have that one friend who dates the biggest tool in the universe and seems completely oblivious to how obviously terrible that person is (some of us have probably even been that friend). No matter how rude, obnoxious, drunken, or unfaithful their partner is, your friend will insist, "No, she's really nice when we're at home" or "Oh, he's just joking around, his dick isn't really made of tyrannosaurus bone," as if they are somehow incapable of seeing the same braying asshole we are. As it turns out, that is precisely what is happening -- they actually cannot see what a crusty dipshit their partner is.
"You're blinded by love ... and his meth smoke!"
There is a specific region in the human brain that is responsible for handling judgment, and under normal circumstances, it lights up like the flaming runway at the end of Die Hard 2 when we're presented with a new situation that requires immediate evaluation, such as meeting somebody for the first time or trying to figure out whether we like the changes to the TGI Fridays menu or if we should flip the table over and go to IHOP instead. We are judgmental creatures by nature, and we are eager to criticize. However, when we're infatuated with something, that judgment-casting region of our brains goes completely dark like a rolling blackout.
We actually become physically incapable of detecting the flaws in the things we love. Apparently, human biology believes it necessary to throw the blinders on in order for our species to survive -- we have a biological imperative to lower our standards.
If unicorns weren't so high and mighty, they'd still be around today.
There is another phenomenon related to this love-blindness called the halo effect, and amazingly it has nothing to do with eliminating your dating competition with a pair of dual-wielded needlers. The halo effect refers to our habit of extending one positive quality that a person possesses to the rest of their character, basically giving us an excuse to like that person. When your friend laughs at the hot girl's terrible joke, he's not faking it -- his brain is telling him, "This person has what you look for in a mating partner, therefore from now on, every little thing she does is magic."
4Our Brains Steer Us Toward the Worst Possible Match
When choosing a partner, we tend to look for somebody with a personality and set of interests closely resembling our own (please note: "fabulous abs" qualifies as a set of interests). As appealing as a torrid love affair with the barista at Starbucks might seem, the relationship is more or less doomed from the start, because at the end of the day you don't know anything about that person, and exposing your genitals in the proximity of scalding coffee is a terrible icebreaker. Conventional wisdom dictates that it's better to find a match, because that way you and your partner are less likely to bore and/or annoy the shit out of each other.

However, if the timeless ballad of Paula Abdul and MC Skat Kat has taught us anything, it's that certain people are only attracted to their complete opposites. It turns out this isn't just a product of terrible decision-making -- there's a neurochemical process at work here that they can do absolutely nothing about it.
Let's talk about hormones again for a second. In many cases, the "opposites attract" phenomenon involves an estrogen-dominant personality being drawn to a testosterone-dominant one, and vice versa. For instance, a nurturing person might be more attracted to an "alpha male" (read: asshole), and a dominant person might be helplessly smitten with a reserved, more submissive person. According to psychologists, these people are unconsciously trying to balance out the deficiencies in their own personalities and form a complementary relationship, sort of like yin and yang, or Tango and Cash.
Which is why their love scene was so passionate but their romance was ultimately fleeting.
There's another kind of opposite-attraction that is so specific, scientists have actually gotten together and named it like the class hamster. It's called the precarious couple effect, and it refers to the pairing of a loud, highly critical woman with a shy, introverted man. Unsurprisingly, the relationships resulting from these pairings are deeply unfulfilling for both parties, in an "I'd rather grundle punch a crocodile than look at my partner's stupid horrible face for one more second" sort of way. So why in the hell do these people get together in the first place?
Well, because in the early stage of a relationship, the wholly incompatible personalities seem appealing in that yin-yang way we discussed above. For example, a man who doesn't talk a lot would find the prospect of an outspoken girlfriend attractive, because her presence would make him feel more comfortable in social situations -- if she's doing all the talking, he doesn't have to. Conversely, a woman who loves to talk would be equally attracted to a man who listens patiently and never tries to interrupt. It is only when they finally start dating that they begin to notice how much they cannot stand each other -- the woman's vocally critical nature grates on the verbally passive man, and his yielding spinelessness drives her fucking insane.
