Memory is an intrinsic part of our life experience. It is critical for learning, and without memories we would have no sense of self. Understanding why some memories stick better than others, as well as accepting their fluidity, helps us …
While runaway cars and vengeful stitched-together humans may be the stuff of science fiction, technology really can take revenge on us. Seeing technology as part of a complex system can help us avoid costly unintended consequences. Here’s …
The act of looking at something changes it – an effect that holds true for people, animals, even atoms. Here’s how the observer effect distorts our world and how we can get a more accurate picture. *** We often forget to factor in the …
