Joseph Doyle is an economist at the Massachusetts Institute of Technology, and he and his clever colleagues looked at different sets of data involving thousands of brothers in both Florida and Denmark, the idea being to discover whether the order we are born affects how we behave.
The results of their study, which were consistent across both locations, showed what us first-borns already knew; our younger siblings have 'issues'...
We can translate what they're saying into a more basic format for you: Parents try harder with their first-borns, and by the time their second child comes around they don't care as much as they used to. We're right, no?
But let us show some support to the second-borns for a minute. Because what the report is saying is that us first-borns didn't set them a good example, and it's no shock that they behave as they do. But wait a second, because if we were only a couple of years old ourselves, that's hardly surprising is it not?
If you are the oldest child in your family and you have a younger sibling, be sure to let them know the scientific proof behind what you had always suspected. And if you yourself are the second-born, be sure to blame your older brother or sister for the terrible example they set you.
