My 3-year-old absolutely loves making pickles with me. I make “quick pickles” for the week every Sunday, and started to invite him to join me, and he is obsessed. He loves cutting the vegetables, putting them in jars, and the smell of the “pickle juice”. It’s become a ritual for us.

My 3-year-old’s favorite word at the moment is “beautiful”. Everything he wants or likes is beautiful, anything he doesn't want is not beautiful.

We've all had the experience of having a solution to a hard problem just "come to us" in a burst of insight when we're not thinking about it. Does this mean our unconscious mind is working on the problem? Not necessarily

It's easy to "sample" successes—opening up Spotify will expose you to successful musicians, bookstores to published authors, shopping to successful entrepreneurs. We don't have a good way of sampling people who tried and didn't have the same success.

There's a scene in an early season of The Walking Dead where an fMRI shows individual neurons, their interconnections, and their real-time electrical activity. It's funny because this is like Star Trek level technology in a modern-day setting

This short line, in a review of the science fiction book Teranesia, is what gave my publication its name: "Cognitive wonder at its challenging best." I loved the term "cognitive wonder" and it seemed to articulate exactly what I wanted to explore (and evoke) in my writing.

If we want to make better predictions and decisions, we should be more like aggregators, holding multiple independent perspectives at once to see what survives. This can be uncomfortable—it means considering different perspectives that may clash with each other.

The “line of purples” is a group of non-spectral colors: because they are formed by a combination of fully saturated red and blue, they do not correspond to any specific wavelength — they’re a combination of long and short ones, with no middle wavelengths.

There's a concept in statistical learning called the "bias-variance tradeoff". One of the things you can take away from it is the value in pluralistic thinking: having many different tools for thinking is better than trying to find the one perfect way

Really young kids (<5) are comically bad at looking for stuff. They'll miss the brightly colored toy or whatever right in front of them while a parent is pointing it out. What's cool is what this tells us about visual attention and its development:

One of the difficulties of science communication: science writers want to stick to the facts, but they are competing with books and articles that have no such constraint.

It doesn’t matter exactly where a brain function happens—to steal a phrase from Jerry Fodor (who was talking more generally about the mind): “[I]t happens somewhere north of the neck. What exactly turns on knowing how far north?”

Ants work together to solve collective problems of the colony without a central planner. For example, each ant following simple rules based on its local observations leads to efficient allocation of foraging resources. Similarly, each neuron in your head follows local rules

It’s true that the top people usually got lucky. But it’s also true that they’re probably quite good. Research suggests that you need to be high quality to be anywhere at the top, but luck is involved in what from the top becomes a breakaway hit.

Steelmanning isn’t just polite. If you’re able to put yourself in the shoes of someone who holds an opposing view, you’re showing you can conceptualize the world the same way they do—you just think your view is a better theory.

Research has shown that in general, having variety among our day-to-day activities also improves happiness. But some psychologists have suggested that the way to combat hedonic adaptation is to make sure there’s novelty in your life.

Reading is a very recent human invention. It first appeared only a few thousand years ago. Why then do we seem to have specialized neural circuitry that, across regions, languages, and even sensory modalities, responds selectively to text?

Our memories are not perfect tape-recorders. Back in the 1930s, Frederic Bartlett did classic memory experiments, giving individuals a short story and days later asking them to repeat it exactly. The story was a Native American ghost story, given to US students.

the bread and butter of much of philosophy—concepts and intuitions—are parts of our psychology. Our concepts come from somewhere, but not some Platonic realm. They're learned, either being built in through evolution or learned from experience.

Gotta rant somewhere: car culture is bloody insane. The city recently put one of those small in-street "pedestrian crossing" signs on the crosswalk right outside my house (I can see it from my window). In the 3 months it's been up, it's been hit by a speeding car 3 times (that I've noticed)

More nuance isn't always better: "Good theories require us to throw out detail to uncover patterns. Newtonian Mechanics don't require you to know the color of the objects. Gravity will work on a red ball as well as on a blue one."
