#1 Our Brains are Addicted to Information

My first job out of university was working for an Architecture firm on the east coast of the US. The job market was particularly tough in the early 90's and the building industry was very fragile during this time. I remember my first staff meeting. Layoffs were looming closer and people were under pressure. One particular woman stood up and proclaimed 'We need more information about what is happening!'. This statement was met with grunts of approval from the rest of the staff.

The manager went on to explain that he posted updates in the coffee room in the morning and afternoon. Note: In 1991 email was just being introduced and no intranet existed at this time.

This was clearly insufficient for some.

The woman responded ' How can we work with knowing what is happening ?' Fear in her voice.

The meeting ended with worried long faces all around.

On the way out the manager asked me how I liked things at the firm.

I replied that people seemed worried and stressed.

He looked at me and frowned slightly,

'Chris you can remember this: people can never get enough information' he said, and walked away.

Since then I have run across this issue many times, and recently discovered one of the factors:

'Our brains are addicted to information'

A good explaination of how this works is from Susan Weinschenk, Ph.D.

Enter dopamine – Neuro scientists have been studying what they call the dopamine system for a while. Dopamine was “discovered” in 1958 by Arvid Carlsson and Nils-Ake Hillarp at the National Heart Institute of Sweden. Dopamine is created in various parts of the brain and is critical in all sorts of brain functions, including thinking, moving, sleeping, mood, attention, and motivation, seeking and reward.

The myth — You may have heard that dopamine controls the “pleasure” systems of the brain: that dopamine makes you feel enjoyment, pleasure, and therefore motivates you to seek out certain behaviors, such as food, sex, and drugs.

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 opoid 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” (opoid) 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 opoid 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).

When you hear the “ding” that you have a text – The dopamine system is especially sensitive to “cues” that a reward is coming. If there is a small, specific cue that signifies that something is going to happen, that sets off our dopamine system. So when there is a sound when a text message or email arrives, or a visual cue, that enhances the addictive effect (for the psychologists out there: remember Pavlov).

140 characters is even more addictive – And the dopamine system is most powerfully stimulated when the information coming in is small so that it doesn’t full satisfy. A short text or twitter (can only be 140 characters!) is ideally suited to send our dopamine system raging.

So the next time you sit in a meeting with your communication department and they insist on more news on the intranet, magazines or press releases just remember:

The dopamine made them do it.
