Real Anti-Racism:
It’s not what you thinkPosted in Thoughts
Shaking the hand of someone you disagree with isn’t as much fun as shouting them down, but it is far more effective.
When you live in small groups on the savanna, as our ancestors did for most of our evolutionary history, it pays to be suspicious of strangers. Other groups were competition. Strangers didn’t drop by for a cup of tea and a friendly chat about our emotional well being. We couldn’t afford to see a stranger as a real person at all. It was an “us versus them” world. Fear and aggression were the only rational responses. People who did well in that world (AKA our ancestors, the people from whom we get our DNA), knew that the only safe thing was to beat strangers with a club first and ask questions later.
Fear of “The Other” is hardwired, and talking about it doesn’t help.
We may not live in small groups on the savanna any more, but our brains don’t know that. For better or worse we are stuck with our evolutionary baggage. Nothing is going to change that. When you encounter someone who your brain perceives as “other”– and by this I mean you personally, dear reader, as well as myself and every other human on the planet — all of that machinery jumps to life in milliseconds. Long before we are consciously aware of anything, our brains are screaming “Danger Will Robinson! Danger!”
Call this tribalism. Call it racism. Call it in-group/out-group dynamics. Call it identity politics. Call it polarization. Call it whatever you like. It all comes down to the same thing. When we perceive someone as other our reactions are hard wired, preconscious, and impossible to turn off.
Good intentions don’t matter. Get high and sing Kumbaya all night. Talk about it until the cows come home. Hold workshops. Post platitudes or scream about it on the internet. If you want to judge the effectiveness of those strategies all you have to do is pick up the paper. The louder the mob screams, the more ground they lose. We’ve tried those approaches. They make things worse, not better.
Quoting Einstein’s famous parable, “Insanity is doing the same thing over and over and expecting different results.”
There is only one solution: Humanize yourself by embracing the humanity of others.
If you perceive someone as other you will respond to them as a threat. There’s nothing we can do about that. Or is there? Take a step back and the answer is obvious. We can’t change how we react to other, but we can change who we perceive as other.
There is going on 70 years of really fascinating sociological, psychological, political and even neurological research that all supports the same conclusion: If you know and respect someone, it’s hard not to care about them. Break bread together, laugh together, talk deeply, listen, show respect (even when it’s difficult), build bridges, find common purpose and work arm in arm.
I could dig into that research, but mercifully for you I won’t. Instead I am going to share an uplifting and illustrative story of what effective anti-racism really looks like.
How did a Black musician change the hearts of hundreds of Klansmen?
Daryl Davis is a Black blues and jazz musician with a very strange hobby. He goes to events like KKK rallies not to shout or protest, but to listen, shake hands, talk, and befriend. Literally hundreds of the Klan members who Daryl Davis has become friends with have renounced the Klan. He has a large collection of their robes, including the robe of a man who, when they met, was the Grand Wizard himself.
Read that last sentence again. Then if you honestly care about fighting racism you owe it to yourself to invest 18 minutes and listen to Daryl Davis’s story in his own words.
This is not your Woke friend’s Anti-Racism.
It feels good to gang up and shout at people. The difference between the shouters and the shoutees makes it really easy to tell who is “us” and who is “them.” Our brains love that. The dopamine flows like a river.
But that is not what Daryl Davis did. There was no shouting about racism. Terms like “White privilege” and “White fragility” were never used. Daryl Davis never complained about microaggressions or political correctness. DEI workshops were not part of the program. Mr. Davis did not wear his feelings on his sleeve. Quite the contrary, Daryl Davis listened even to open hatred and tried to understand where it was coming from. There was no talk of victims and oppressors. There were no social media attacks or calls for deplatforming. There was no virtue signaling about Wokeness.
Instead, Daryl Davis treated those who were predisposed to hate him with dignity and respect. He listened. He questioned. He befriended. He humanized himself by seeing and acknowledging the humanity of others, including those with whom he deeply disagreed. In the process he did what few have ever accomplished. Daryl Davis changed the hearts of hundreds of the most committed racists in the nation.
This is what real, effective anti-racism looks like. And as Davis mentions at the end of his talk, if he can do it, so can we.

Schools in the Time of COVID

You don’t tug on Superman’s cape. You don’t spit into the wind. Yes, schools are desperately important to kids. No, COVID-19 doesn’t care, and COVID is making the rules right now. Attempts to open schools this fall will fail of their own accord. The relevant question is how to meet the needs of children, families and the community in the face of that reality.

Over his 30 year career as an internationally known astrophysicist, Dr. Jeff Hester was a key member of the team that repaired the Hubble Space Telescope. With one foot always on the frontiers of knowledge, he has been mentor, coach, team leader, award-winning teacher, administrator and speaker, to name a few of the hats he has worn. His Hubble image, the Pillars of Creation, was chosen by Time Magazine as among the 100 most influential photographs in history.

It’s Genetic
Returning engineering to its roots
Genetic algorithms are revolutionizing our world by reconnecting engineering with its four-billion-year-old roots.
Republished from my monthly Astronomy Magazine column, For Your Consideration.
I recall the first time that I saw the famous movie of the windy November morning in 1940 when the Tacoma Narrows Bridge, connecting Tacoma and the Kitsap Peninsula across Puget Sound in Washington, tore itself to pieces. There she was, “Galloping Gertie” as the bridge was known, wildly bucking and twisting in a 40 mph (60 km/h) wind. Then, suddenly, in a matter of only a few seconds, the third-longest suspension bridge ever built at the time was no more! To this day, the Tacoma Narrows Bridge remains a textbook example of engineering gone wrong. Structures are subject to vibrations, and if you aren’t careful, those vibrations can spell big trouble.
Fighting vibrations with a different approach to design
Enter Professor Andy Keane. The year is 1994, and Keane and his colleagues at Southampton University in the UK are working to design a much smaller bridge — a truss — that is as vibration-free as possible. They aren’t worried about the extreme oscillations that destroyed Gertie, but they do care about the slight vibrations that would cripple a delicate instrument like an astronomical satellite. They start with a traditional design, but that’s where tradition ends. Instead of using their knowledge and insight to improve the design in clever ways, they metaphorically throw intelligence out the window. They hand the job over to a computer and then kick back and wait to see what happens.
The computer itself is kept intentionally dumb. It doesn’t know anything about engineering design principles. It only can do two things. First, it can make new virtual trusses by combining and randomly changing the properties of existing trusses. Second, it can compare trusses and tell better from worse. Armed with no other tricks up its sleeve, the computer marches along, blindly turning the crank:
Step 1: Make a new generation of trusses by shuffling and making random changes in the previous generation.
Step 2: Evaluate the new trusses, and toss the ones that don’t work so well.
Step 3: Repeat. Again, and again, and again …
Ten generations and over 1,000 virtual trusses later, the computer’s best effort is lopsided and twisted and irregular. It looks more grown than designed. Nobody understands it or has the faintest clue how it works. But it does work. It works very well. The vibrations have been improved by more than 20,000 percent!

This truss, designed by a genetic algorithm, may not look like much, but it performs wildly better than a traditional truss designed by humans using standard engineering principles. (Photo courtesy Andy Keane.)
When the right conditions are met, evolution isn’t a theory; it is applied logic.
Keane was not the first to take this approach to design, and he certainly wasn’t the last. Two decades later, such unguided, blind algorithms are revolutionizing our approach to the shapes of airplane wings and turbine blades, new molecules for industrial and pharmaceutical uses, pattern recognition, communications networks, investment strategies, cancer treatments, and hundreds of other applications.
At their core, all of these applications have two things in common: (1) the better an item performs, the more likely its properties will be retained; and (2) when surviving properties are passed on from one generation to the next, variations occur. As long as these two conditions are met, properties will evolve from generation to generation as items become better and better suited to their task.
By the way, life satisfies these two conditions. When evolutionary biologists talk about the first condition, they call it “selection.” When they talk about the second condition, they call it “heredity with variation.” And like any other system that satisfies these conditions, life evolves. Logically, life can’t help but evolve! In one sense, engineers who employ genetic algorithms to evolve technologies are doing something new. But in a deeper sense, they are returning engineering to its roots, tapping the power of the mindless algorithm that has been shaping life for almost 4 billion years.
If you want to understand the algorithm of evolution, talk to a cutting-edge design engineer.
The public discussion of biological evolution is undeniably muddled. In part that is because people tend to approach it from the wrong direction. Darwin’s voyage on the Beagle deserves to be the stuff of legend, but if you want to understand evolution, forget about finch beaks or fossils. Instead, talk to a working engineer who is using genetic algorithms to evolve a truss.
Once you’ve wrapped your head around how and why a truss gets so good so quickly, you have the understanding you need to approach evolution as scientists do. You can use that understanding of evolution to make predictions about the world and then see whether those predictions hold true. When you do that, you discover that the predictions of evolution are in remarkable accord with all that we see. From the fossil record to the common chemistry of life, to the shared structure of different species — and now to pharmaceuticals, jet engines, and bridges — we live in a world crafted by evolution’s unguided hand.
The Tacoma Narrows Bridge collapsed because it acted like an unstable airplane wing. If you are interested in the wind-driven resonance (called aeroelastic flutter) that caused the collapse, watch this cool video of a computer simulation from the Natural Hazard Modeling Lab at The University of Notre Dame.
