Anyway,as the idea became more popular, psychologists realized that they should probably do some actual research to find out if birth order theory was actually true.

Based on a handful of early studies, some psychologists are pretty convinced that you can connect birth order to specific big five traits like oldest children are more conscientious and neurotic while youngest children are more open to new experiences, and this approach is really appealing it sounds totally plausible right. But those earlier studies have a lot of flaws and the more recent research with bigger better design studies hasn’t found much of a connection between birth order and Big five personality traits. One of the problems with those smaller was that they often depended on one sibling self-reporting, their personalities and those of their siblings. So if the researcher were interviewing an oldest
