In 2007, the team at the University of Washington Institute for Learning and Brain Sciences conducted an experiment with 18-month old toddlers found they become so sensitive to the subtlest psychological changes in a person's expressions that it might actually explain why they always cry when you come anywhere near them. They can feel the deep-seeded hatred for all things baby under that fake smile of yours.
It gets weirder.
See, their mind-reading doesn't end with fellow humans. A study from Brigham Young University has shown that kids not even six-months old who have never been confronted with a dog in their entire lives, could easily match the different barks of a canine with their corresponding pictures. Which is interesting because HOLY s**t BABIES CAN UNDERSTAND ANIMALS!
Sadly, these amazing abilities get lost the minute the babies learn how to talk and get their hands on Twitter, becoming the modern age nonverbal-communication cripples. Before that though, they are basically Lil' Professor Xaviers.
You are... utterly disgusted and... thoroughly depressed. Did I get that right, daddy?
