Claims by Matthew MacDougall (5)
Consciousness is sensing your own brain working
Consciousness is likely far less magical than instincts suggest; a useful analog is that just as we have an intuitive sense of feeling our skin being touched, consciousness is that same level of sensory mapping applied to the brain's own thought processes—the sensation of feeling parts of your brain being active—rather than any quantum field effect or warping of space-time.
Polished rocks model of team disagreement
A good team operates in a sweet spot where members forcefully and passionately defend their positions yet remain able to accept information and change their ideas when wrong—like polishing rocks by putting hard things in a hard container and spinning so they bash against each other and a more refined product emerges—which requires overriding the primate brain's tendency to treat conceding an argument as a loss of standing.
Brain controls nearly all bodily systems
The brain controls or massively influences almost everything the body does—it is hard to name a bodily function not directly controlled or influenced by it, since even bone healing involves the hypothalamus and pituitary coordinating the endocrine system to affect blood calcium—which makes the brain an under-explored area for primary treatments of conditions like fertility, blood pressure, and mood that aren't obviously brain problems.
All human problems reduce to neurochemistry
Everything humans can conceive of as important—perception, relative values, and solutions to all problems—is literally contained in the skull, and all the great triumphs and horrific tragedies of human history boil down to neurochemistry, so gaining a little control over that provides people the option to do better.
Robots lack latitude to react to surprises in surgery
Human surgeons are general-purpose machines that can dynamically change the plan mid-surgery when surprised (such as discovering a hidden aneurysm), whereas current surgical robots operate according to a fixed program with little latitude to react to changing conditions, though AI may dramatically broaden the parameters for robot responsiveness in the future the way self-driving cars handle unexpected events.
