According to two psychologists interviewed by The Telegraph, there could be more to just picking a seat. Passengers who prefer the window seat may be more selfish, while as those who prefer the aisle may be more reserved.
“Passengers who favor the window seat like to be in control, tend to take an ‘every man for themselves’ attitude towards life, and are often more easily irritable,” Dr. Becky Spelman, chief psychologist at Harley Street’s Private Therapy Clinic, told The Telegraph. “They also like to ‘nest’ and prefer to exist in their own bubble.”
Behavioral psychologist Jo Hemmings agreed.
“Aisle passengers are often more sociable and definitely more amenable as people; they are also more likely to be restless fliers and less adept at sleeping on planes,” Hemmings added.
Personally, I prefer the aisle seat because of exactly the reason above! I am restless and can't sleep on planes! lol
