It's a question that's perplexed philosophers for centuries and scientists for decades: Where does consciousness come from? Neuroscientist Christof Koch, chief scientific officer at the Allen Institute for Brain Science, thinks he has an answer.
The human brain is capable of 1016 processes per second, which makes it far more powerful than any computer currently in existence. But that doesn't mean our brains don't have major limitations. The lowly calculator can do math thousands of times better than we can, and our memories are often less than useless — plus, we're subject to cognitive biases, those annoying glitches in our thinking that cause us to make questionable decisions and reach erroneous conclusions. Here are a dozen of the most common and pernicious cognitive biases that you need to know about.
In the rush of everyday life, many people say they crave a moment of solitude, but a startling new study finds that people don’t really enjoy spending even 10 minutes alone with their thoughts. In fact, we find our own musings so unsatisfying that, in research done at the University of Virginia, many people chose to administer painful electric shocks to themselves rather than sit in quiet contemplation, researchers from that university and Harvard reported Thursday.
We have vain brains; we see ourselves as better than we really are. We like to think that we exercise free will, that put into a situation where we were challenged to do something we thought unacceptable then we'd refuse. But, if you believe that, then you are probably deluded.
