The evolutionary basis of rigidity: Locks in cells, minds, and society

Feedbacks leading to alternative stable modes of behavior occur on levels varying from the cell and the mind to societies. The tendency to lock into a certain pattern comes at the cost of the ability to adjust to new situations. The resulting rigidity limits the ability of persons, groups, and companies to respond to new problems, and some even suggest that it may have contributed to the collapse of ancient societies. In the face of these negative effects, it may seem surprising that lock-in situations are so ubiquitous. Here, we show that the tendency to lock into one of several alternative modes usually serves an apparent purpose. In cells, it filters out noise, and allows a well-defined and consistent behavior once a certain threshold is passed. Basically, the same holds for the attitudes and behavior of individuals and groups. This functionality is not surprising as it has evolved through selection for fitness. Understanding why rigidity makes sense may help in finding ways to avoid traps in situations where flexible response and innovation are needed

A message from magic to science: seeing how the brain can be tricked may strengthen our thinking

Scientific discoveries rely on creative thinking, and several authors have explored similarities in and differences between creativity in the sciences and that in the arts. Here we explore possible ways in which science can learn from the arts, focusing specifically on experiences derived from the art of magic and on the limitations of human cognition. Generations of stage magicians or “illusionists” have made sophisticated use of the weaknesses in human systems of perception and interpretation. We highlight three important principles of magic tricks, including: (1) the audience see what it expects, (2) it is blind to all but the focus of attention, and (3) ideas spring predictably from a primed mind. These principles highlight a number of important tendencies, which we argue are shortcomings in the ability of scientists to perceive the world, and which scientists need to be aware of. Consciously addressing these shortcomings may help scientists improve their creativity, and will strengthen their capacity to address complex and global challenges. © 2015 by the author(s).
