It turns out, when you look at your phone you are making other people want to do it too. According to the DailyMail.co.uk, researchers in Italy found that out of 184 people half of them looked at their phone within 30 seconds of seeing someone else do the same.
Findings suggest checking your phone is very similar to the idea that yawning can be contagious. The biggest difference the study found was that yawning can lead to group bonding. When people are all looking at their phones people are more likely to be antisocial.
