Terms like geometric morphometrics and pareidolia aren’t generally important to people designing or buying cars, however they were significant in a recent study that found that people see faces when looking at vehicles, and typically they prefer ones that look powerful.

Pareidolia is an occurrence in which people actually see faces in various things from clouds to inkblots to cars. A recent study was based on this concept and used geometric morphometrics to let participants rank vehicles on how they looked, using traits that are human like disgusted, sad or extroverted.

The results of the study confirmed that pretty much all people like cars that are powerful looking, like the BMW 5 Series. Also, people tend to shy away from designs that are feeble-looking, like the Toyota Prius because they worry that they won’t be as sturdy and will require a good auto warranty.

Who knows if this research will determine the future designs of cars, but it might mean that we will see more big-mouthed grilles on the roads.
