My blog represents my personal experiences and perspectives. This includes many anecdotes from my life and from my medical practice. I have been scrupulous to anonymize all medical anecdotes and to avoid ever belittling or making fun of patients. (I often make fun of and criticize myself, my colleagues, and the institutions where I have worked.)
Our brains are lying to us.
Our brains do three things:
• Collect, organize, and store information.
• Use that information to identify possible patterns and create models.
• Use those patterns and models to produce behaviors that increase our probability of surviving and reproducing.
(In response to the person who insisted on believing the science he learned in high school - decades ago.)
Cognitive neuroscience shows us that humans fall on a continuum between two poles that I like to label as the Warrior Perspective and the Scout Perspective. (With a shoutout to Julia Galef, whose interests are the philosophy of science and applied rationality, and who has written about this.)
I was asked recently on social media if we are to ignore XX versus XY chromosomes as a scientific identifier of gender and sex? My short answer was that science gave up on XX/XY as an identifier of sex a generation ago. My much longer answer follows.
People forget two important facts about Nature:
• Nature does not deal in binary categories.
• Nature depends on diversity for survival.
Consider the math on the timeline of our species: 99.5% of our history was spent as hunter-gatherers (family groups, clans, small tribes) and only 0.5% since about 10,000 BCE and the development of farming, animal husbandry, fixed populations centers with governance (cities).
A recent Boston Review has a good article on close reading.
My family likes to complain that I am a pessimist and tell me I would be happier if I were more optimistic. They don’t understand. Some of the unhappiest people I know are optimists, because they falsely assume that optimism produces good outcomes. Their optimism feels to them like a magical talisman that will protect them. When their positive thinking does not shield them from bad outcomes they feel betrayed by Fate, often taking it personally, and sometimes becoming bitter.

Here is an image that illustrates the central concept of this essay: things are seldom what they seem. Almost everyone who views this image describes it as red strawberries:
Even when told there are no red pixels in the image, almost everyone still sees the strawberries as red.
