Dopamine is not addictive (2017)

To me it seems random actions cause dopamin production.
Like, how does the body know that it should release more dopamin when I scroll HN than when I learn Rust, or ride my bike?
Learning Rust, while stimulating, does not has that tight reward loop, so you are not addicted to learning Rust but to scrolling HN as your easy dopamin dispenser. You need to invest a lot of effort into learning something complex as Rust (or painting, or whatever which require a good amount of knowledge and practice.) before getting that dopamin reward.
That is, it is the habit drug. It helps you remember the precise nature of recurrent rewards, and presumably is "intended" to help you get better are arriving at the reward.
Makes much more sense now, thanks!
This is what's broken in ADHD and why people affected profit from increasing dopamine with some stimulants.
I've seen some dreck on PsychologyToday. After the author used a weak metaphor as an excuse to lead the article with Kim Kardashian's bust, and slammed other opinions as "kindergarten brain science", I didn't bother to see if there was anything subtle or worthwhile here. It's not the fault of readers if most of them were alienated quickly and bailed out. It's the fault of poor writing and editing that were indicative of time being wasted.
Is this why activities associated with bad 'dopamine habits' are so strongly correlated with said the bad habits that involved dopamine?
After having quit smoking, I find myself desperately wanting to do the 'break thing' whereby you stop what you're doing, take 5 minutes to just stand, relax and and enjoy the moment for a second while ignoring the stress.
I honestly don't even think I want the cigarette, just everything else about that experience.
Parallel universe you (possibly with a goatee) that did the "break thing" but never smoked during a break will want to take a break but has no association with cigarettes or smoking. Their desire for a break remains, maybe with the same strength, but with no desire for a cigarette.
(In hindsight I probably shouldn't have been encouraging a harmful drug addiction, but it was more tongue-in-cheek than anything.)
On Hacker News? Not likely. Everyone's a well informed 10xer who doesn't just go shooting his mouth off with the first thought that pops into his mind.
Any basic psychology course or textbook will provide the context to understand this. You could look at it as operant conditioning, and there are probably much more nuanced and data driven explanations that I'm ignorant of.
The cognitive effort required to "learn Rust" is much greater than scrolling social media, watching YouTube, etc. and doesn't provide the same reward/stimulation. The brain will always crave the easier sources of dopamine and prefers to be on auto-pilot.
In my opinion having done a few of them, a dopamine detox is likely a waste of time, although disconnecting from electronics can be a nice break if you need/want that.
You will never want to start learning Rust because there's always easier sources of dopamine for your brain to indulge in. The key is starting anyways. Open the Rust docs and start trying. I only require myself to do 10 minutes of coding per day. Usually, after the 10 minutes my brain is already engaged and I continue for multiple hours on that momentum. Occasionally I'm having an off day and can't get myself to focus/engage properly for whatever reason and after the 10 minutes or the one small change I wanted to make is over I stop.
Even just the 10 minutes each day is infinitely more than continuing to do nothing.
That's a pseudoscientific narrative. It's not literally based on the science of dopamine. It's based on the pop-science dopamine metaphor.
It's nowhere near scientifically accurate. Don't read too much into it.
Do you know of anything that elucidates the oversimplifications of dopamine popscience?
Edit: This does a good job: https://www.theguardian.com/science/2013/feb/03/dopamine-the...
I think dopamine is not "reward", but "anticipation of reward". It's how long your brain can wait untill it evaluates the success of an action. Upon success you gain more dopamine, which enables you to do new tasks.
So dopamine is essential in executive functions like planning and focus.
The problem arises from the evolutionary adaptations we carry, like finding scarce cheap energy like easy carbs (pre agricultural world had nothing sweeter than a carrot), which gives us dopamine from eating sweets today. Your brain also likes new information, which does not leave your model of reality in shambles. There are probably other mundane "self-efficacy" experiences rewarded, like voting and commenting.
I assume there is some feedback loop which will make the pleasant feeling of actual reward greater, the less "anticipation of reward" dopamine was spend. This is basically a scarcity adapted self-improvement algorithm, which is defunct in modern abundance.
This is a great, succinct summary of (some of) dopamines role (from our limited understanding) in the brain.
It’s complex, but based on the tools we have to manipulate and measure dopamine, it’s a part of addiction but it doesn’t explain everything.
And dopamine plays an important role in other functions like movement (I.e. Parkinson’s disease).
You could literally say this about most major neurotransmitters.
Frankly, the fact that the scientific community allows things like the chemical imbalance theory and dopamine addiction theories and other pseudoscience to gain such mainstream acceptance delegitimizes the institution. Scientists should not be defending such statements in the wishy-washy way you did above.
I'm not sure where I defended the chemical imbalance theory in my comment.
In biological, let alone neurological systems, the notion of cause is far less discrete than it is in a reductive area such as basic physics. Many of the long term effects in these kinds of systems arise in circumstances where there are clearly feedback loops and many of them overlapping. One component may be involved in the dynamics of addiction, regulating motor functions, and learning, and each of these phenomena involve many components. The neurotrash that pushes the message that dopamine is somehow the causal component in the process of addiction appeals to the reductive interest in seeing every effect as the consequence of a straightforward cause.
This kind of thinking in public perception also might be the consequence of the pharma industry pushing a narrative of "chemical imbalances" being at the root of behavioral and psychological problems, discharging from this picture factors on many other levels such as past experiences, mental associations, social and familial conditions, economic circumstances, etc... all of which can contribute to addiction as a phenomena.
I disagree. He explains why the technical distinction is important.
His main point is this: dopamine production alone does not indicate that an activity is addictive. He even highlights absurd conclusions drawn using this logic -- that gun ownership is addictive, for example.
To put it another way: even if dopamine release is required to produce addiction, not all dopamine release can lead to addiction.
Dopamine itself does not produce euphoria[1]; it has a variety of roles in the brain; and it is produced during many non-addictive activities (e.g. skiing or finishing a large puzzle).
As the author touches upon, and other researchers confirm in more depth[1][2][3], the reality of dopamine production is complex. Not all dopamine production is the same. It varies by brain region, quantity, and duration, all of which vary its effect on the brain.
> "However, while the acute reinforcing effects of drugs of abuse that depend on such fast DA increases are likely 'necessary' for the development of addiction, they are clearly not 'sufficient.' Repeated drug exposure causes changes in DA brain function that take time to develop because they result from secondary neuroadaptations in other neurotransmitter systems (e.g. glutamate and perhaps also γ-aminobutyiric acid (GABA)) that, eventually, affect additional brain circuits modulated by DA."[2]

The article is actually addressing the issue where dopamine in natural amounts is considered addictive and harmful, so it doesn’t need to address that.
It's a little bit like saying, hey, I took a road and I went to the wrong destination. Let me look at the road and understand this process. It is paved with asphalt, so maybe asphalt is the problem. Maybe the road surface is too good and easily drivable. Which doesn't make sense, because (a) roads that take you to good destinations are also paved with asphalt and (b) you ended up at a bad destination because of a wrong turn rather than because of the road conditions.
Like, if something is wrong with your car, it would be nice if there was some magic elixir you can add to fix it, and indeed any auto parts store has dozens. They have fuel injector cleaner, engine stabilizer, stop leak, no smoke additive... But if there is a real problem, it probably requires doing something to fix the way moving parts are interacting, not just adding a little fluid.
Which seems to me suggestive of an analogy with how people* talking about adjusting the levels of brain chemicals, when surely it's got to be a dynamic process that isn't working right.
*as in, the people who write the patient info pamphlets for psychotropic drugs
However, this doesn't mean that one cannot be addicted to dopamine. Lab rats will submit themselves to physical harm to get more dopamine and humans given a dopamine button keep pressing it for more. This is explained in the book "The Willpower Instinct".
It's probably the case though that you would only see a psychologist like the author of this article for an addiction to a true reward chemical (like opioids). A dopamine addiction is more likely to be something like checking your phone for messages every few minutes.
The usefulness of dopamine is to provide motivation. So unfortunately the solution to a perceived dopamine problem isn't to broadly have less dopamine (then you won't want to get off the couch), but to somehow have less associated with the activity you don't want to do and more associated with the activity you do want to do.
- their environment (residence, city, state, country)
- their job, career, or academic pursuit
- their romantic life
- their friends
People have completely transformed as a result of one move, with an example being someone from a small town in the Midwest moving to New York City. I think everyday productivity hacks, motivation hacks, anti-habits, etc...are marginally overrated. They could even be damaging if they keep you in an environment or circumstance that you are fundamentally incompatible with. Conversely, big structural life changes are underrated.
If someone reading this found the above to be true (or not) in their personal life, please weigh in.
Choice quote IMO.
Whenever I see this sort of thing it makes me want to scream.
I do agree with his statement that we need to talk more about the complex reasons for that behavior on top of behavioral conditioning, and that people caught in those cycles can and should leverage the means that we have at our disposal to undo that conditioning when it is harmful to them (with professional help as needed). But I think it is absolutely valid to talk about how behavioral conditioning is intentionally leveraged in the design of many products we use, in casinos, etc. And that it is not something that people can or do consciously notice.
Before people can help themselves, they need to even realize there is a problem in the first place, and that is one of the dangerous things about behavioral conditioning. Conditioning is the very mechanism by which we learn new behaviors that become integrated into our life: and as such, it is very easy for a person to fall prey to operant conditioning and for it to just feel like "life as normal," even when the patterns in your life have actually changed dramatically.
In particular, I think it's important for us to be aware of behavioral conditioning as an intentional design choice of the products we use and the entertainment we engage in. The more we are consciously aware of it, the more we can develop the sort of meta-cognition that allows us to notice when we fall into patterns of conditioning that are harming us more than helping us. (note that you can also be conditioned to engage in behaviors that are helpful too! So being aware of what you are conditioning yourself for is as important as whether/when you are being conditioned)
90 billion neurons in our brain, interconnected in some combinatorial number of ways, but all our behavior and inner world boils down to the interaction of a few dozen neurotransmitters. Yup, sounds about right.
Our brain "code" is messier than anything mad programmers could have produced. Global variables are generally not a good practice, so of course our brain has global variables. And of course they are reused for completely unrelated things, for example lactation and the immune system, because life is like that. Life never read about pure functions and design patterns and will happily use floating point numbers as pointers and jump between two instructions.
Back to the subject, I think it is just a case of circular reasoning. Dopamine is part of the reward system, and addictive stuff cause dopamine to be released. To limit addiction, limit things that cause dopamine to be released. So, to limit addiction, you have to limit things that are addictive.
Can you expand on this a bit more?
Serotonin, the other "pleasurable" neurotransmitter does pretty much everything.
It makes sense from an evolutionary point of view. It is easier to repurpose a molecule we can already produce than to build an entirely new pathway.
Same goes for pop understandings of science. My favorite is "survival of the fittest" for Darwinian evolutionary theory, which is basically wrong as it's vastly oversimplified and prone to enormous misunderstandings. A more accurate and modern version would be "differential rates of reproduction of patterns of genetic information that influence the formation of phenotypes in proportion to those phenotypes' performance of said reproduction." Not as catchy, and much harder to use to rationalize popular cultural and political fads.
This template seems like an extension of Betteridge's law of headlines
Is there a movement to increase dopamine access in middle America I'm unaware of?
