In 2007, the neuroscientist Sabrina Tom slid volunteers into an fMRI scanner at UCLA and offered them coin-flip gambles. Win twenty dollars or lose twenty. Win thirty or lose ten. Will you take the bet? Most people refused any gamble where the potential loss exceeded about half the potential gain. The scans showed why: as potential losses grew, the brain’s reward regions responded more sharply to what could be lost than to what could be gained. Loss aversion — losing something hurts roughly twice as much as gaining it feels good — was visible in the tissue.
That same year, evolutionary psychologists were calling loss aversion a design feature — a calibrated response to environments where losing a day’s food could mean death but gaining extra food meant only marginally better odds. Meanwhile, behavioral economists were calling it a violation of rational choice theory. A rational agent’s choices shouldn’t depend on how identical information is described — but under loss aversion, they do. Frame a surgery as having a 90% survival rate and patients choose it; frame it as having a 10% mortality rate and they hesitate.
Three traditions, three accounts, all well-evidenced — and not three ways of saying the same thing. The neuroscientist suggests modulating the neural response. The behavioral economist suggests reframing the choice. The evolutionary psychologist suggests understanding the adaptive function before overriding it. Nobody has a principled way of deciding among them, because the field has never settled a prior question: what is a cognitive bias? Read more »

Allopathy and homeopathy are two contrasting theories of medicine. Allo, meaning other, and homo, meaning same, indicate how suffering (pathos) is cured in these two approaches. Modern medicine, speaking generally, is based on the principle of allopathy, meaning that sickness is counteracted by healing and therapeutic treatments; homeopathy, often considered alternative medicine or pseudoscience, is based on the idea that “like cures like,” so rather than introducing an antidote to an illness, the medicine used is meant to produce a response similar to the illness itself, stimulating the body’s natural healing mechanisms and curing the underlying ailment.

Political discussions and debates leave me cold. That’s because I abhor conflict, and politics always seem to be accompanied by disagreements, fights, raised voices, and anger. When I think about the hot topics in the 60s and 70s, many of them centered on matters of race, I associate those times with images of red-faced individuals confronting one another, not infrequently accompanied by fists, even guns. Sometimes soldiers or militias or mobs.
KK: One of my best friends from high school, Brian Boland, was a regular on the main stage at Second City, which helped define improvisational comedy and produced so many famous comic actors. He’s also an accomplished voice actor and has been in some ads our readers have probably seen (like for Geico). He brought two of his colleagues and they each took on characters in the story, “The Ad Man After Dark.” It was amazing to witness how they brought the characters to life and entertained the audience. 

Do birds have a sense of beauty? Do they, or does any animal, have an aesthetic sense? Do they respond to beauty in ways we might find familiar – with a feeling of awe, suffused with attraction, mixed with joy? Do they seek it out, and perhaps even work to fashion it from their surroundings? Darwin thought so, and made the idea the subject of his second major work, The Descent of Man (1871). In it, he outlined a mechanism by which the sense of beauty might, by shaping mating preferences, work to shape the form of insects, fish, and birds in a manner parallel to the better known process of natural selection. The resulting beauty of form, sound, or movement, Darwin argued, is neither the result of intelligent design, nor a necessary indication of superior fitness. Beauty, as

Over the past year, there has been significant movement in AI risk management, with leading providers publishing safety frameworks over the past year that function as AI risk management. However, the problem is that these are not actually proper risk management when you compare them to established practice in other high-risk industries.
