There’s an interesting article in The Guardian about what is driving our fixation with self-presentation and attention grabbing.
"Attention is other people thinking about you, and if there were ever humans who didn’t need it, they are now extinct. “Attention is one of the most valuable resources in existence for social animals,” says Dr Geoff MacDonald, a psychologist at the University of Toronto with an interest in human connection. “It was literally a matter of life and death. The people who didn’t feel good around others, or didn’t feel bad when they were separated from others, wouldn’t have the motivation to do the things that are required to pass their genes down the generations.”
