addictions
Why train the elephant?

If given total control, the “elephant” side makes choices detrimental to future success and happiness.
Problems with an untrained elephant…
Decisions dominated by the short-term, impulsive self tend to reduce future happiness and success due to:
1. Excessive future discounting
2. Finding negative addictions
3. Avoiding positive addictions
Problems with excessive future discounting
Future discounting The rate at which you
are willing to trade immediate experience for future experience.
Today, I can drive away in a new car with
nothing down!
In the future, I’m paying 14% interest on an asset with disappearing value.
Excessive future discounting
The rate at which we are willing to trade current experience for future experience reflects our rate of future discounting.
Today I can spend $100 borrowed on my credit card
In the future, I will pay $150 in accumulated interest/penalties
Where will you change from saying “yes” to the saying “no”?
Future discounting
If you were in a mall and wanted to buy something, how much would you be willing to pay for $100 right now?
Today $100 borrowed
Next month $99 owed.
Next month $95 owed.
Next month $100 owed.
Next month $101 owed.
Next month $102 owed.
Next month $105 owed.

The elephant-side may make “fun” choices, but you could end up broke, obese, ignorant, hung over, diseased, and dying!
Future discounting and success in children
“Those 4-year-old children who delayed gratification longer in certain laboratory situations developed into more cognitively and socially competent adolescents, achieving higher scholastic performance and coping better with frustration and stress.”

Time horizon and wealth building
In 1998 about 5,000 people were asked:“In planning your saving and spending, which of the following time periods is most important to you,
the next few months, the next year, the next few years, the next 5-10 years, or longer than 10 years?”
Comparing people with the same starting wealth, did those with longer time horizons accumulate more
wealth in the following 8 years?
Wealth growth and time horizon
Comparing with the wealth growth of other people with the same starting wealth:
Answer in 1998: Financial Planning Time Horizon
1998-2006 change in wealth v. Others with identical starting wealth
next few months No significant differencethe next year No significant differencethe next few years No significant differencethe next 5-10 years + $157,427 more than otherslonger than 10 years + $240,699 more than others
Other research finds:Planning ahead→wealth“Why do similar households end up with very different levels of wealth?”
“We use new and unique survey data to assess these differences and to measure each household’s ‘propensity to plan.’ We show that those with a higher such propensity spend more time developing financial plans, and that this shift in planning is associated with increased wealth.”

Finding negative addictions

The elephant is experiential. Consequently, the elephant side craves experiential variety.
Variety enhances experiential utility
Variety is important because “diminishing marginal utility” changes preferences. When enjoyment drops, we switch to another choice.
Hot Dogs Consumed
Utility from Each Hot Dog
1 +102 +43 04 -15 -46 -10
But, unlimited experimentation is risky due to negative addiction “traps”
The rider “knows” that meth generates a high (and has terrible future consequences).
Although the elephant doesn’t care about the future, it hasn’t experienced the effects, so it isn’t tempted.
Addiction alters the ability of the rider to control future choices.
The elephant gradually loses ability to experience other types of enjoyment, and focuses exclusively on the addiction.
Negative addictions as a path dependent preference
A negative addiction is • initially pleasurable • gradually requires more
consumption to reach the same level of satisfaction• lowers satisfaction from
other items (Anhedonia)• creates future harm
Anhedonia
The inability to experience pleasure from normally pleasurable life events
Can result from the use of artificial dopamine stimulants like cocaine or amphetamines (negative addictions)
The negative addiction trap
How does a negative addiction affect– Future Choices?– Future Satisfaction?– The Future Brain?
Work in groups of 2-5 people. After the video, discuss and have one person write down your thoughts

“Rationality” inside a negative addiction
“[previous research shows] people who discount the future heavily are more likely to become addicted.
Our result establishes the converse, that harmful addictions induce even rational persons to discount the future more heavily, which may in turn lead them to become more addicted.”
Becker, G. (Chicago) & Mulligan, C. (Chicago) , 1997, The endogenous determination of time preference. Quarterly Journal of Economics, 113, p.744
“Rationality” inside a negative addiction
We could work through the mathematics of the model from Nobel prize winning economist Gary Becker…
but, instead, let’s try…

Translating Gary Becker using Jeff Spicoli
• Look, it’s not like he is giving up a future career as a brain surgeon or something.• Even if he could have done that
at one point in his life, that is no longer an option due to the effects of addiction. • So he isn’t giving up that much
more by continuing to diminish his (already limited) future prospects.
Rationality inside a negative addiction
The initial meth user may be giving up a lot of future opportunities for using.
After continued use, she may not be giving up as many future opportunities to keep using.
Path dependent preference: negative addiction
A low concern for the future
addictive consumption (diminishes future options)
Diminished future options means additional loss from further consumption is less
Non addictive consumption ↓ reward
Anhedonia ↑
Applying concepts to practice
An Interview with Kathleen T. Brady, M.D., Ph.D., Professor and Director of the Clinical Neuroscience Division at the Medical University of South Carolina.
Anhedonia and early intervention
http://www.hbo.com/addiction/thefilm/supplemental/621_kathleen_brady.htmlFrom start of “How Does Addiction Affect the Brain?” until just before start of “What aspects of a person’s life need to be addressed in recovery?” (Ending segment of chapter 1 on the website)
Negative addictions and the paradox of consumption variety
• Unlimited consumption experimenting risks negative addiction.
• Negative addiction leads to exclusive focus on the addictive item.
Unlimited consumption variety for immediate experience
Negative addiction
Extreme focus on addiction with poor life experiences
Problems with an untrained elephant…
Decisions dominated by the short-term, impulsive self, tend to reduce future happiness and success due to:
1. Excessive future discounting
2. Finding negative addictions
3. Avoiding positive addictions
A negative addiction is • initially pleasurable • gradually requires
more consumption to reach the same level of satisfaction• lowers satisfaction
from other items (Anhedonia)• creates future harm
A positive addiction is • initially not very
enjoyable• gradually becomes
more enjoyable with experience• creates future
benefits
Discussion question
Can you think of things that are 1. Good for you (or are at least not harmful)2. May not be initially enjoyable 3. Gradually become more enjoyable with
continued experience?
Work in groups of 2-5 people, discuss and have one person write down your ideas
Potential positive addictions
• Education in a particular field of study• Exercise• Religious practice• Reading complex novels or non-fiction• Watching opera, ballet, football, equestrian,
basketball • Playing a musical instrument or a sport
Consumption capital and positive addictions
Experience leads to greater understanding, appreciation, and enjoyment. This accumulated experience resulting in greater enjoyment is called “consumption capital”
Sing, o muse of the pernicious anger of Achilles…
Path dependent preference: positive addictions
Low current utility but with future benefits
Practice increases enjoyment of future consumption
Increased current utility leads to more practice
Consumption Capital ↑External
Benefits ↑
Planned and unplanned focus
Unintentional focus• Ignoring long-term
outcomes• Negative addictions• Increasing focus on
addictive substance• Decreasing
opportunities
Intentional focus• Planning for long-
term outcomes• Positive addictions• Increasing focus on
long-term behaviors• Increasing
opportunities
If you feed it, it will growEarly decisions are like yeast (a.k.a. “path dependent preferences”)• An early decision for short-
term, visceral choice can reduce future options and lead to preference for more short-term, visceral choices
• An early decision for long-term goal achievement can lead to more opportunities for goal achievement
Overcoming misleading experienceIn the case of both negative and positive addictions, initial experience is misleading.• Negative addictions provide
initial positive feedback• Positive addictions provide
initial negative feedback
Overcoming misleading experienceBecause of this false experience feedback, ideal outcomes require externally influencing the choice environment.
