Taste the Science: The 253rd Evolutionary Lens with Bret Weinstein and Heather Heying

In this 253rd in a series of live discussions with Bret Weinstein and Heather Heying (both PhDs in Biology), we talk about the state of the world through an evolutionary lens.

In this week’s episode, we follow the science to fewer cow farts. Bovear, an FDA approved product that is fed to cattle to reduce their production of methane, is the result of yet more reductionist, metric-heavy research that conflates complex systems with complicated ones. Bill Gates approves, though, so what could go wrong? We discuss ruminant biology, the actual Carbon impact of grazing cattle, and some other great new products from the makers of Bovear, including “the world’s first-ever flavor created by artificial intelligence.” Then: why is the BBC’s disinformation wing concerned about what Bret said on Diary of a CEO? What happened to journalism? Finally: it’s Thanksgiving tomorrow. Liberals are supposed to be high in openness—consider being open to the differing views of your friends and family, and have a wonderful time together.

The Essence of Woke Explained | DarkHorse 318

Bret Weinstein and Heather Heying explore the pressures to prematurely close off possibilities by examining woke" as a social phenomenon where dissent is pressured and consensus is enforced.

"...There's banish, we're not gonna platform you because you've lost your mind and there's coercion. We're gonna get you back on board with the consensus. And those two things are basically a choice. Either you get back on board with the consensus or you're out."

Avoiding certainty is hard but necessary. Bret & Heather use real cases to think scientifically about the world in Episode 318, "Careful Thinking in Reckless Times."

"The nested sets nature of logic, which branching diagrams can reveal in a different way than if you just nested the sets within parentheses or something, can show you that it could be Tyler Robinson and still not have him be some lone gun nut, which is exactly what you have established here." Heather Heying

Bret Weinstein reacts to the Melania Trump AI teachers:

"I get it. And it’s not that it is impossible to imagine robotic teachers doing an excellent job, but it is stunning to watch a sophisticated person fail to recognize what happens when you think that that’s what you’re going to produce, and you set it in motion.

Let me point out that Wikipedia has many of the advantages that Melania is describing in this video. It is completely democratizing of knowledge, such that it doesn’t matter where on earth you are. If you have an internet connection, you’ve got Wikipedia. It’s like an extension of your own mind, and it will make us all brilliant.

Now, of course, that didn’t happen, did it? Wikipedia is a hellscape of misinformation, much of it targeted based on a political agenda. We are less certain of what we know, and less capable of reasoning on our own.

Now, that doesn’t all come from Wikipedia, but my point is the promise of Wikipedia was not realized. And what we got instead is arguably worse than what we had before it was ...

If everything feels confusing right now, this is for you.

In Ep. 318 of the Evolutionary Lens, Bret Weinstein & Heather Heying discuss how to understand our universe: through logic, intuition, and probability, through keeping track of what we believe, and being willing to change our minds.

Avoiding certainty is difficult, but necessary. Using examples of: who killed Charlie Kirk, and whether the venue where he was speaking suggests black magic, we discuss how to make sense of the world in a scientific way.

Failure of Imagination

When zero sum thinking is a mindset

If you haven’t listened to Avraham Burg and Tucker’s conversation, I highly recommend it. As someone who is fascinated with the Israeli mindset, I found the conversation to have a wealth of information. Burg is a former Speaker of the Knesset and interim president of Israel. He grew up inside the system and spent decades at the center of Israeli political life. And in this interview, he genuinely transformed how I think about those in the Israeli political scene.

Here are the quotes that stood out to me the most:


1)

> “We Israelis live in a reality where a constitution can be seen as a threat.”

Unfortunately, I am starting to think more Americans feel this way too. A lot of Americans, especially when it comes to vaccines or figures like Charlie Kirk, seem to adopt what I would call “Sam Harrisonian” thinking—where we must trust the institutions because institutions need to be trusted. Therefore, it’s okay to ask questions… but only after the endless ...
