When a baby reaches for one stuffed animal in a room filled with others just like it, that seemingly random choice is very bad news for those unpicked toys: the baby has likely just decided she doesn’t like what she didn’t choose.
Though researchers have long known that adults build unconscious biases over a lifetime of making choices between things that are essentially the same, the new Johns Hopkins University finding that even babies engage in this phenomenon demonstrates that this way of justifying choice is intuitive and somehow fundamental to the human experience.
“The act of making a choice changes how we feel about our options,” said co-author Alex Silver, a former Johns Hopkins undergraduate who’s now a graduate student in cognitive psychology at the University of Pittsburgh. “Even infants who are really just at the start of making choices for themselves have this bias.”
The findings are published
