It depends what you're googling. Some actually don't have a personality, or much of one, and don't understand some human emotions, so have to learn to mimic them.
If you're googling stuff like this, which is what Chris Watts googled even though he'd been married for 8 years with two kids, then you and others you come into contact with are maybe in trouble.
“What do you feel when someone tells you they love you” and “How does it feel when someone says I love you.”
If you have to google that, then you don't have a normal human range of emotions. People who do, don't need to google stuff like that.
Chris Watts is a Narcissistic Sociopath, possibly somewhere on the autistic spectrum too.
I am weary of people who say they feel like they have no personality tbh, but it all depends on what you're googling.
