The study also found that women were more attracted to men when other women in the photo were smiling at him, but proceed with caution here. The researchers also recommend selfies with genuine smiles, the kind that crinkles up your eye at the edges, and a little head tilt.

Couples psychologist Peter Pearson told Tech Insider that the best way for singletons to figure out what they want is to "date as much as they can manage or tolerate." Why?

Because you can't actually figure out what works for you (and what doesn't) until you meet people with a variety of traits and see what it's like to hang with them.

It turns out that people that are insecure but romantically successful manage to channel their nervous tics into behaviors that are linked with other, more attractive qualities.

A nervous talker can come across as a brilliant conversationalist, and eagerness to please is easily interpreted as niceness.

A 2013 Stanford study published in the American Journal of Sociology analyzed almost 1,000 dates to figure out what makes people click.

The researchers set up a series of speed dating events for Stanford graduate students, recorded each individual date, and used software to analyze those conversations.

Everyone in the dating game spends untold time, money, and emotional energy trying to find a nice person to chill with on the couch while you both actually watch Netflix — but somehow, most of us still feel like we're striking out constantly. That means thousands and thousands of study subjects have made all kinds of dating mistakes so that you and I don't have to.

Luckily, because of the ubiquity of dating (and researchers' enduring fondness for studying all varieties of mating dances), we have a huge bounty of research to draw on.

And the data bears this out — Match, the dating website that also owns Tinder and Ok Cupid, surveyed its users and found that a great first date is a drink or two over the course of a couple of hours.

It makes sense: Alcohol, as most of us know, lowers inhibitions.

These studies, surveys, and experts can help us all figure out what works — and maybe even up our chances.
