For complex beings, humans aren’t that great at perceiving time. We’re especially bad at measuring time in the short term – seconds, minutes and hours. Our sense of how much time is passing is subjective, easily biased by other things that are going on around us, our mood or what we’re doing at the time.
A recent paper seeks to explore why this might be. While the answer doesn’t really come as a surprise, it is interesting to note that it can be reproduced in a lab.
