Myth and Motivation: On Dopamine

There are contradicting views and explanations of what dopamine is and does and how much we can intentionally affect it. However, the commonly heard notions of scrolling for dopamine hits, detoxing from dopamine, dopamine drains, and craving dopamine, appear to be more like a story we've constructed to understand our actions than a scientific explanation, and I'm not convinced it's the best narrative to help us change our behaviours, particularly around tech-based habits. 

As a hormone, it's released by the adrenal glands (above the kidneys) into the bloodstream for slower, more general communications where it primarily helps to regulate our immune system. As a neurotransmitter, it provides fast, local comms between neurons in the brain where it does a lot of different things including affecting movement, memory, motivation, mood, and mornings (waking up). It makes up 80% of the "catecholamine content" in our brain, the ingredients that prepare us for action. Our levels fluctuate throughout each day, so you don't have to try to cram all your work into the early hours of the morning.

It's largely discussed as the heart of our quest for pleasure, yet for decades studies have concluded that dopamine doesn't affect pleasure, since we get a dopamine release before a rewarding activity, not after we've completed it. Instead, it affects how the brain decides if an action is worth the effort. A 2020 study found that increasing it with meds like Ritalin can motivate people to perform harder physical tasks. People with higher levels of dopamine are more likely to choose a harder task with a higher reward than an easier, low-reward task. Low dopamine doesn't reduce focus, but it's believed it provokes giving more weight to the perceived cost of an activity instead of the potential reward. Lower levels lead us to save energy.

So why do we think we crave it or, paradoxically, need to try to intentionally deplete it?

On Legislating Kindness

If kind, other-centred behaviour isn't entirely natural to us, then should it be legislated (more than it already is)?


Many old timey philosophers agree that happiness is predicated on an increase in pleasure and decrease in pain, and that just seem like common sense. Yet all too often the choices we make don’t lead towards our intended outcome of increased pleasure; instead, we make choices that lead us towards misery. We want a clean world, but we drive everywhere. We want a strong uptown core, but we don’t stop shopping at Wal-Mart. We want civilization to continue with beautiful nature to hike in and plentiful conveniences, but we're definitely not about to stop using fossil fuels or eating beef. 

Plato might say our problem is that we don’t have the skill of measurement, and he'd call for better education. Epicurus called the same thing a lack of prudence, and he ditched the city to live in a garden with a careful selection of friends. And B.F. Skinner would agree that our immediate reinforcers or punishers seem much larger than distant rewards and punishments. It all boils down to a society full of people making poor choices. Most of us. There are some people who measure well because they seem to just care more about making wise decisions while the rest can’t be bothered to worry about long-term consequences. I think what makes the difference between those that measure well and those that don’t isn’t so much a skill they learned, but a personal disposition they inherited.

Which mean it's a fools errand to try to teach it.

On Progressive Education - Seven Questions

I recently watched a film, Most Likely to Succeed, which has inspired a lengthy post about educational reform.


FIRST, A BIT ON DEWEY AND SKINNER: 

(If educational theory isn't your bag, then just scroll down to the next bit.)

Is it true that, "If we teach today's students as we taught yesterday's, we rob them of tomorrow"? It's highly probable that John Dewey never said it despite the misattribution making the rounds online. If you read just one or two of his essays, it's clearly not his typical wording and syntax (and now we can easily "command-F" our way through his books). Regardless the source, I believe we also do a disservice to education by tossing what we did yesterday in favour of the newest idea. New isn't always better.

Here's what Dewey does say, though,
