Dopamine creates a feedback loop of want and discover:

It’s all about seeking — The latest research, though is changing this view. Instead of dopamine causing us to experience pleasure, the latest research shows that dopamine causes seeking behavior. Dopamine causes us to want, desire, seek out, and search. It increases our general level of arousal and our goal-directed behavior. (From an evolutionary stand-point this is critical. The dopamine seeking system keeps us motivated to move through our world, learn, and survive). It’s not just about physical needs such as food, or sex, but also about abstract concepts. Dopamine makes us curious about ideas and fuels our searching for information. The latest research shows that it is the opioid system (separate from dopamine) that makes us feel pleasure.

Wanting vs. liking – According to Kent Berridge, these two systems, the “wanting” (dopamine) and the “liking” (opioid) are complementary. The wanting system propels us to action and the liking system makes us feel satisfied and therefore pause our seeking. If our seeking isn’t turned off at least for a little while, then we start to run in an endless loop. The latest research shows that the dopamine system is stronger than the opioid system. We seek more than we are satisfied (back to evolution… seeking is more likely to keep us alive than sitting around in a satisfied stupor).

A dopamine induced loop – With the internet, twitter, and texting we now have almost instant gratification of our desire to seek. Want to talk to someone right away? Send a text and they respond in a few seconds. Want to look up some information? Just type it into google. What to see what your friends are up to? Go to twitter or facebook. We get into a dopamine induced loop… dopamine starts us seeking, then we get rewarded for the seeking which makes us seek more. It becomes harder and harder to stop looking at email, stop texting, stop checking our cell phones to see if we have a message or a new text.

Anticipation is better than getting— Brain scan research shows that our brains show more stimulation and activity when we ANTICIPATE a reward than when we get one. Research on rats shows that if you destroy dopamine neurons, rats can walk, chew, and swallow, but will starve to death even when food is right next to them. They have lost the desire to go get the food.

More, more, more – Although wanting and liking are related, research also shows that the dopamine system doesn’t have satiety built in. It is possible for the dopamine system to keep saying “more more more”,  seeking even when we have found the information. During that google exploration we know that we have the answer to the question we originally asked, and yet we find ourselves looking for more information and more and more.

Unpredictable is the key — Dopamine is also stimulated by unpredictability. When something happens that is not exactly predictable, that stimulates the dopamine system. Think about these electronic gadgets and devices. Our emails and twitters and texts show up, but we don’t know exactly when they will or who they will be from. It’s unpredictable. This is exactly what stimulates the dopamine system. It’s the same system at work for gambling and slot machines. (For those of you reading this who are “old school” psychologists, you may remember “variable reinforcement schedules”. Dopamine is involved in variable reinforcement schedules. This is why these are so powerful).

Adam are you copy pasting this? Is this a bot doing it?A RIL type scrape would be awesome! though thar be dragons.

I copy pasted but you're right that a bot or smarter bookmarklet would be more desirable.
