You might think it's creepy... or maybe kinda cool. In any case, a very invasive technology has been developed by scientists that allows them to scan a person's brain and accurately predict behaviors before the person acts.
This may sound Sci-Fi and futuristic, but this controversial research is advancing rapidly and creating much fodder for ethics debates.
Implications - The computer works by learning patterns of brain activity that corresponds to certain thoughts. Afterwards, it scans the brain for these signatures as a source of predicting thoughts. So far, this has been tested on people with a 70% accuracy, which isn't high, but isn't low either.
This is a pretty controversial development considering how there are people who are very cautious about revealing their private thoughts.
