Here are some of the most interesting things I learned this year:

1. Employees who use Firefox or Chrome have a 15% higher retention rate and report more satisfaction at work than employees who use Internet Explorer or Safari. This is because they’re less likely to accept the default way of doing things.

2. Doctors are 14% more likely to diagnose a child with ADHD on October 31, not because there are more kids with ADHD, but because the kids are excited to go trick-or-treating.

3. It takes nine out of ten Americans to agree on a policy in order for it to have a 50% chance of being approved.

4. When men feel their masculinity is threatened, they are 24 percentage-points more likely to want to buy an SUV. They are also willing to pay $7,320 more than non-threatened men for the same vehicle.
