Google is destroying your memory
 | | Well,
OK, maybe not totally destroying it, just making it unnecessary to rely
on friends, libraries, books, notes, and other forms of “transactive
memory” (external systems), thanks to the rise of Internet search
engines, Wikipedia, and other Internet tools. So says Columbia
University psychologist Betsy Sparrow, co-author of an article in
Science Express. “Since the advent … more… |
How to preserve competing memories by zapping your brain
 | | Attention,
mind-control victims: mad scientists want to zap your brain. But you
knew that. It’s a problem every student has when cramming for an exam:
