Below is my attempt to list all human needs ranked according to their typical importance (from most important to least). Thanks for the idea, Maslow! I'm defining a "need" here as something non-replaceable (i.e., you can't just substitute it for something else), which, if substantially unsatisfied, would inhibit well-being for the vast majority of people. You might say that you...

As I see it, there are three main causes for our struggles to see the truth on any particular topic: 1. Mimicry: when our in-group promotes falsity that we copy 2. Incentives: when we predict that knowing the truth would feel bad or harm our objectives 3. Complexity: when the truth is hard to figure out Examples: 1. Mimicry • Some are Christians because all their friends...

From a scientific or statistical standpoint, it seems ridiculous to think one data point can teach us much. Even a study with ten data points is laughably small. It's also really common to see people over-react to a single experience they've had (e.g., "I know I don't like Taiwanese food because I tried it once") or to an anecdote (e.g., "I'm convinced this supplement will work because my frie...

Written: May 5, 2021 | Released: June 18, 2021 People often talk about what a problem "confirmation bias" is. But we rarely discuss what causes so many of us to search for information in a biased way. Let's explore some of the forces: 1. Echo chambers: our routine sources of information tend to support our worldview. Much of this is due to social ties (we tend to talk to people who ...

Written: May 3, 2021 | Released: July 16, 2021 Fascinatingly, human minds and machine learning algorithms are subject to some of the same biases and prediction problems. This is probably not a coincidence - learning has fundamental challenges. Here is a list of some issues that afflict both minds and machines: 1. Recency Bias For both humans and machine learning algorithms, the most r...

It's common to try to explain things as either due to nature OR nurture. Or, at best, we say: some percentage of the variation in outcome is due to genes, and some percentage is due to the environment. It's important to remember, though, that outcomes can be a complex interaction between the two. Consider this: Our genetically-influenced traits impact what environments we seek ou...

There is an important division between people who want to improve the world that few seem to be aware of. Inspired by Julia Galef's new book (The Scout Mindset), I'll call this division: Soldier Altruists vs. Scout Altruists. 1. Soldier Altruists think it's obvious how to improve the world and that we just need to execute those obvious steps. They see the barriers to a better world a...

In science (and when developing hypotheses more generally), it is very common to come across situations where a variable of interest (let’s call this the dependent variable, “Y”) is strongly correlated with at least two other variables (let’s call them “A” and “B”). Here are some examples:  If you’re a psychology researcher investigating possible causes of depression (Y), you may have trouble...

If you ever have trouble starting on something that's important or find yourself procrastinating on a project, you may find it useful to notice what you feel at that moment and design your approach based on it. Here is a list of "feeling-based" strategies that may help you get started on what you have trouble getting yourself to do: If you are feeling: 1. unsure of where to start-> th...

More often than not, I find that postmodernist thought obscures rather than illuminates. But I also see useful elements in it. Here's my very un-postmodern attempt to "steel man" (i.e., find the value in) ideas related to postmodernism: 1. Narratives Serve Power - powerful groups do tend to have a substantial influence on narratives, beliefs, and what's "normal." Something "obvious" o...
