Do opposites attract?

In your opinion, do you think people with extremely different personalities end up in relationships more often than those who are similar?
Will depends person to person but i've saw women being nice caring people dating the complete opposite : total douchbags. And it was explicit, meaning that the guy never hidden his true personality. It's the same thing with different views on politics sometimes.

But overall people never end-up with the strict opposite but not the similar either, it can't be possible to find an exact carbon copy of yourself in a partner, especially in hobbies, views, opinions etc...

And it's a good thing sometimes having someone not thinking the same way than you
