Let's face it, no one wants to date a cheater but often times we don't see the signs our boyfriend or girlfriend is a shady little liar. Forget him answering his phone in the closet or her being less affectionate with you. Is your girlfriend blonde? Is your guy addicted to Twitter? What's his name? Through journal studies and surveys users on cheating websites, science seems to know exactly what makes someone more likely to be unfaithful.

But does someone's height or name really make them any more (or less) likely to stray — or are these things strange coincidences? Well, only those who have dated these 9 people may know the truth. Until you do the dating legwork, we'll give you the facts and let you make an educated decision yourself.

1. Tall Guys
We are telling you this not just because short guys make us swoon. Last week, a study from extra-marital dating site, IllicitEncounters.com, told us that dudes over 5'10" are twice as likely to cheat on their partner. Knew they were up to no good up there.

2. Rock N' Roll Fans
These two are the kind of sketch balls your mama warned you about. Another survey from IllicitEncounter.com found that 41 percent of cheaters prefer rock music to all other genres. Your best bet for a loyal partner? Rap lovers.

3. The French
What can you expect in a relationship with the best lovers in the world? Wine, cheese and an affair, says science. According to LELO, a luxury sex toy brand, who surveyed the globe about bedroom habits, 75 percent of the French admit to cheating.

4. Twitter Users
Shocker: social media can be harmful your romantic relationship! While this isn't too surprising, research from the University of Missouri shows those who tweet cheat. The more often a person uses Twitter, the more often they have relationship conflicts, like affairs. #TimeToCloseTheLaptop

5. Female Teachers
Which professions are more likely to stray? According to an AshleyMadison.com survey of its users, the typical cheating wife is likely to be a teacher. Someone's got to teach these ladies a lesson — just don't call tech support ...

6. Guys Who Work In IT
Don't be fooled by their soft hoodies, hipster glasses and patience when it comes to restoring your iPhone (you really should start backing up!) — These guys are sneaky, cheating hubbies, according to the same Ashley Madison survey that revealed unfaithful wives are often teachers.

7. Guys Named Wayne
An easy giveaway he's sleeping with someone else? His name. A study
of 2,000 women found Wayne ranked as the least trustworthy name in love.
