Neurodiversity: Many mental 'deficits' are really hidden strengths
The more diverse minds we have, the better we are as a population.
Heather Heying: Neurodiversity is a pretty new term, and I’m grateful—very grateful for it.
It gets to something that is absolutely real and has been hard to discuss before it existed.
That said, I’m not sure I have a perfect definition. It recognizes a fact that we are not singular, that we are not all identical, that we have a variation of brains, of connectivity, of aptitudes, of weaknesses, of blind spots, and of sensitivities, and of capabilities.
People on the autism spectrum who are very functional, in my experience, tend to have extraordinary analytical skills and also often, actually, insight into social interactions so long as they’re not the ones participating.
And so you have, I’ve had a number of autistic students actually point out to me dynamics that were emerging in classrooms that I hadn’t yet seen, and once they were pointed out I could see, and these are the same students who have a very hard time recognizing when it is or is not time to speak or get up or walk through the middle of the classroom and such.
There are a number of ways to be neurodiverse.
We have names for some conditions that actually represent ends of continuum.
Dyslexia is a big one. These are going to sound like they’re coming out of left field, but color blindness, left-handedness... in each of those cases being what in evolutionary biology we call the non-dominant phenotype.
Sorry. I’m a lefty. That’s the one of those that I belong to as a group. And about ten percent of people across all cultures (that have been studied) are left-handed. It’s a persistent, stable, rare phenotype, which suggests that it’s adaptive, that it’s persistent, it’s complex, and it provides the different wiring of the brain associated with being a left-hander provides benefit in the social group in which left-handers show up.
I mean we can put together analyses for why being a left-hander might allow you to approach a physical problem differently than a right-hander would have a harder time solving, but the different wiring of the brain allows for different approaches as well.
Similarly with color blindness that it might be really easy to say, “Well, okay, that just is going to give you some ability to see past color and to see patterns that aren’t color based,” perhaps, but I suspect that there’s wiring in the brain that is associated with color blindness that also allows for enhanced abilities that are different from those who are color-sighted.
Dyslexia for sure. Dyslexia is obviously a very modern condition because writing is a very modern condition. So as an evolutionary biologist when I say modern I mean thousands of years. So dyslexia is modern in terms of thousands of years, and language was always about sound and never about writing until recently, and so the lessened ability—it’s almost never an inability, but the lessened ability—to process written symbols into meaning in your head looks to me like it’s a trade-off relationship with the ability to engage in real time and speech. And that’s not to say that all of us can’t learn through practice to be better at any number of these skills, but that being born with what the world is calling a deficit is almost always going to exist in a trade-off relationship with some often hidden strength.
Color-blindness. Left-handedness. Dyslexia. Autism. These are all different ways in which the brain is rewired differently than the norm. But Heather Heying, evolutionary biologist and former Professor at Evergreen State College, is saying that these so-called differences are really strengths. For example, she relays us a story about her autistic students being far more adept at spotting social dynamics emerging in the classroom, long before non-autistic students. And left-handed people are often way more creative than their righty counterparts. Evolution might suggest that we need these differences to be stronger as a whole.

A man's skeleton, found facedown with his hands bound, was unearthed near an ancient ceremonial circle during a high speed rail excavation project.
- A skeleton representing a man who was tossed face down into a ditch nearly 2,500 years ago with his hands bound in front of his hips was dug up during an excavation outside of London.
- The discovery was made during a high speed rail project that has been a bonanza for archaeology, as the area is home to more than 60 ancient sites along the planned route.
- An ornate grave of a high status individual from the Roman period and an ancient ceremonial circle were also discovered during the excavations.
Foul play?<p>A skeleton representing a man who was tossed face down into a ditch nearly 2,500 years ago with his hands bound in front of his hips was dug up during a high speed rail excavation.</p><p>The positioning of the remains have led archaeologists to suspect that the man may have been a victim of an ancient murder or execution. Though any bindings have since decomposed, his hands were positioned together and pinned under his pelvis. There was also no sign of a grave or coffin. </p><p>"He seems to have had his hands tied, and he was face-down in the bottom of the ditch," <a href="https://www.livescience.com/iron-age-murder-victim-england.html" target="_blank">said archaeologist Rachel Wood</a>, who led the excavation. "There are not many ways that you end up that way."</p><p>Currently, archaeologists are examining the skeleton to uncover more information about the circumstances of the man's death. Fragments of pottery found in the ditch may offer some clues as to exactly when the man died. </p><p>"If he was struck across the head with a heavy object, you could find a mark of that on the back of the skull," Wood said to <a href="https://www.livescience.com/iron-age-murder-victim-england.html" target="_blank">Live Science</a>. "If he was stabbed, you could find blade marks on the ribs. So we're hoping to find something like that, to tell us how he died."</p>
Other discoveries at Wellwick Farm<p>The grim discovery was made at Wellwick Farm near Wendover. That is about 15 miles north-west of the outskirts of London, where <a href="https://www.hs2.org.uk/building-hs2/hs2-green-corridor/" target="_blank">a tunnel</a> is going to be built as part of a HS2 high-speed rail project due to open between London and several northern cities sometime after 2028. The infrastructure project has been something of a bonanza for archaeology as the area is home to more than 60 ancient sites along the planned route that are now being excavated before construction begins. </p><p>The farm sits less than a mile away from the ancient highway <a href="http://web.stanford.edu/group/texttechnologies/cgi-bin/stanfordnottingham/places/?icknield" target="_blank">Icknield Way</a> that runs along the tops of the Chiltern Hills. The route (now mostly trails) has been used since prehistoric times. Evidence at Wellwick Farm indicates that from the Neolithic to the Medieval eras, humans have occupied the region for more than 4,000 years, making it a rich area for archaeological finds. </p><p>Wood and her colleagues found some evidence of an ancient village occupied from the late Bronze Age (more than 3,000 years ago) until the Roman Empire's invasion of southern England about 2,000 years ago. At the site were the remains of animal pens, pits for disposing food, and a roundhouse — a standard British dwelling during the Bronze Age constructed with a circular plan made of stone or wood topped with a conical thatched roof.</p>

The ceremonial burial site included a circular ditch (about 60 feet across) at the center, and was a bit of a distance away from the ditch where the (suspected) murder victim was uncovered. Additionally, archaeologists found an ornately detailed grave near the sacred burial site that dates back to the Roman period, hundreds of years later when the original Bronze Age burial site would have been overgrown.</p><p>The newer grave from the Roman period encapsulated an adult skeleton contained in a lead-lined coffin. It's likely that the outer coffin had been made of wood that rotted away. Since it was clearly an ornate burial, the occupant of the grave was probably a person of high status who could afford such a lavish burial. However, according to Wood, no treasures or tokens had been discovered. </p>

Though the wooden posts have rotted away, signs of the post holes remain. It's thought to date from the Neolithic period to 5,000 years ago, according to Wood.</p><p>This circle would have had a diameter stretching 210 feet across and consisted of two rings of hundreds of posts. There would have been an entry gap to the south-west. Five posts in the very center of the circle aligned with that same gap, which, according to Wood, appeared to have been in the direction of the rising sun on the day of the midwinter solstice. </p><p>Similar Neolithic timber circles have been discovered around Great Britain, such as one near <a href="https://bigthink.com/culture-religion/stonehenge-sarsens" target="_blank">Stonehenge</a> that is considered to date back to around the same time. </p>
Research reveals a new evolutionary feature that separates humans from other primates.
- Researchers find a new feature of human evolution.
- Humans have evolved to use less water per day than other primates.
- The nose is one of the factors that allows humans to be water efficient.

Being skeptical isn't just about being contrarian. It's about asking the right questions of ourselves and others to gain understanding.
- It's not always easy to tell the difference between objective truth and what we believe to be true. Separating facts from opinions, according to skeptic Michael Shermer, theoretical physicist Lawrence Krauss, and others, requires research, self-reflection, and time.
- Recognizing your own biases and those of others, avoiding echo chambers, actively seeking out opposing voices, and asking smart, testable questions are a few of the ways that skepticism can be a useful tool for learning and growth.
- As Derren Brown points out, being "skeptical of skepticism" can also lead to interesting revelations and teach us new things about ourselves and our psychology.
