Sharper brains switch to a 'not what you know, but who you know' mindset online and on social media, study shows

Forming social connections online and via social media reduces how much people engage with and learn from the content posted but significantly boosts their networking performance, according to new research. The study, published in Journal of Experimental Social Psychology, led by the University of Bristol in the UK in partnership with the University at Buffalo, State University of New York in the US, found this shift of focus from learning about the actual content to concentrating on the related social connections is more marked among people with a better memory.
