Use available tools in non-naive ways.
Practice this skill on every day routine.
Learn from commercial sector. Apply marketing theories at the kitchen, apply economical theories in education.

There is no such thing as a “neutral” design.
Seemingly arbitrary decisions, such as where to locate the bathrooms, will have subtle influences on how the people who use the building interact.
// ASK: Architect, what are common patterns in influencing human behavior in architecture? (eg. should trips to bathroom encourage to meet colleagues?)
“If a man sees a fly, he aims at it.”
Easy for people to go their own way; they do not want to burden those who want to exercise their freedom.
“paternalistic” – influence choices in a way that will make choosers better off, as judged by themselves.
Alternative choices are not blocked, fenced off, or significantly burdened.
Nudge – self-consciously attempting to move people in directions that will make their lives better.
Freedom to choose is the best safeguard against bad choice architecture.
Intervention must be easy and cheap to avoid. Nudges are not mandates. Putting the fruit at eye level counts as a nudge. Banning junk food does not.
Understanding of human behaviour can be improved by appreciating how people systematically go wrong.
Knowing something about the cognitive system has allowed others to discover systematic biases in the way we think.
We are not homo economicus; we are homo sapiens.
Overweight is necessarily failing to act rationally,
Humans cannot afford to think deeply about every choice they have to make.
We should let ourselves be advised by professionals – we get trainers in gyms, financial [poradce] in accounting, and many more. Do not avoid guidance in other fields.
Econs – not required to make perfect forecasts, but required to make unbiased forecasts. Forecasts can be wrong, but can’t be systematically wrong in a predictable direction.
The false assumption is that almost all people, almost all of the time, make choices that are in their best interest or at the very least are better than the choices that would be
made by someone else.
System 1 – Automatic System (uncontrolled, effortless, associative, fast, unconscious, skilled)
System 2 – Reflective System (controlled, effortful, deductive, slow, self-aware, rule-following)
Automatic System is your gut reaction and the Reflective System is your conscious thought.
Automatic Systems always win over Reflective ones.
If an option is designated as the “default,” it will attract a large market share.
Utilize in organ donations.
We use rules of thumb because most of the time they are quick and useful.
Anchor, the number you know, and adjust in the direction you think is appropriate.

Governments are likely to allocate their resources in a way that fits with people’s fears rather than in response to the most likely danger.
Stereotypes are sometimes right!
Story: Linda – bank teller and active in the feminist movement.
When they see the outcomes of random processes, they often detect patterns that they think have great meaning but in fact are just due to chance.
People to confuse random fluctuations with causal patterns.
Examples: cancer clusters
“above average” effect – driving, sex, professors, marriages
Unrealistic optimism can explain a lot of individual risk taking, espe- cially in the domain of risks to life and health.
If people are reminded of a bad event, they may not con- tinue to be so optimistic.
1 of 10 is dead versus 90 of 100 are alive.
Discount versus extra fee for full price.
Loss aversion – Losing something makes you twice as miserable as gaining the same thing makes you happy.

yawns are contagious
most people learn from others. This is usually good, of course. Learning from others is how individuals and societies develop. But many of our biggest misconceptions also come from others.
Obesity is contagious. If your best friends get fat, your risk of gaining weight goes up.
Maybe parents should worry less about which college their kids go to and more about which roommate they get.
Live, work and be with successful people

Positive nudge – simply inform people about what other people are doing. successes!
people’s intentions, they affect people’s conduct.
If people are asked whether they intend to eat certain foods, to diet, or to exercise, their answers to the questions will affect their behavior
Ask yourself what you want to be
Ask students what they want to become
Use in workout
The nudge provided by asking people what they intend to do can be accentuated by asking them when and how they plan to do it.
At one extreme are what might be called investment goods, such as exercise, flossing, and dieting. For these goods the costs are borne immediately, but the benefits are delayed. living healthy
Hard problems become easier with practice.
Learning is most likely if people get immediate, clear feedback after each try.
For example, we usually get feedback only on the options we select, not the ones we reject.

Want to know the secret to successful innovation? Simple. You need to create innovations that are designed to be chosen.
The best way to help Humans improve their performance is to provide feedback.
Some cell phones, aimed at the elderly, include a fake dial tone, for similar reasons. Handy in design
Painting white over white – Pink when wet but turns white when dry.
Asset-allocation decision – where to allocate your assets (stocks, bonds, money).
Attitudes toward risk depend on the frequency with which investors monitor their portfolios.
Judge people mood about company by looking at the percentage of money being invested in stocks by new participants who have just made the decision.
Initial allocation is never changed.
In the house with both kinds of candy, every child selected one of each candy. In contrast, only 48 percent of the children picked one of each candy when they were choosing in sequence in two houses.
There is no correlation between the allocation to company stock and subsequent stock performance.
By contrast, those who have the option, but not the requirement, to take the employer’s match in the form of company stock allocate only 18 percent of their own funds to company stock.10
A dollar in company stock is worth less than half the value of a dollar in a mutual fund!
A natural alternative would be to treat company stock just like every other investment, without any kind of preference.
Nudges can be social influences.
People are more likely to engage in self-examinations for skin and breast cancer if they are told not about the reduced risk if they do so but about the in- creased risk if they fail to do so.
Most vulnerable population, specifically the poor and the poorly educated.

individuals should be able to decide what is to be done with and to their bodies.
shifts the default rule – opportunity to register their unwillingness to donate.
the harder it is to register your unwillingness to participate, the less libertarian the policy becomes.
In Germany, which uses an opt-in system, only 12 percent of the citizens gave their consent, whereas in Austria, nearly everyone (99 percent) did.
Renewal of your driver’s license would be accompanied by a requirement that you check a box stating your organ donation preferences.

Many doctors must pay $100,000, or significantly more, in insurance bills every year. Your medical bill reflects those costs.
“defensive medicine,” ordering expensive but unnecessary treatments for patients, or refusing to provide risky but beneficial treatments, simply in order to avoid liability.
To respect the liberty of religious groups while protecting individual freedom in general, we propose that marriage, as such, should be completely privatised. Under our proposal, the word marriage would no longer appear in any laws, and marriage licenses would no longer be offered or recognised by any level of government.
Eliminate the ambiguity of word marriage – now refers both to an official legal status and to a religious one.
Instead of channeling every partnership into the same one-size-fits-all arrangement of state marriage, couples could choose the marriage-granting organisation that best suits their needs and desires.
As long as state grants official marriage licences, marriage will has immense importance.
When people marry, they receive not only material benefits but also a kind of official legitimacy from a state.
Marriage should be similar to book writing partnership. Official licensing system no longer fits modern reality.
Benefits of marriage from state:
Unfortunate division between married and single. Unnecessary polarisation and confusion about relationships between state-sponsored and religious marriage.
People take private commitments seriously even without government licensing.
Nothing prevents people from making commitments through the civil union.
Marriage should be for private institutions, not for the state.
Religious organisations would be free to set their own rules regarding who could marry.
Set explicit formula for dealing with exiting formal civil union.
Marriage does not limit entry, but police exit – it make it difficult for people to abandon their commitments to one another. – form of nudge. If divorce is difficult, then marriages are more likely to be stable.
Marriage is solution to a self-control problem. Similar to voluntarily entering other ways of protecting long-term interest.
Protect children and more vulnerable. But marriage is not the right tool for this protection. Other legal institutions are more suitable.
Extreme unrealistic optimism about marriage.
Paradox: Accurate estimate of divorce rate of others, but total bias of their marriage.
Reflective system wants to be charitable, but Automatic System doesn't get around to it.
Commit to increasing donations automatically every year/month.
Keeping track of donations for tax return is burdensome.
Your bank will take care of that for you.
No sensible choice architect would design the current income tax system.
Tax report would be pre filled by IRS, you will only check it and send it back.
Social help in achieving goals and aspirations.
Commitments with finance or social status (e-mails to friends announcing your success or failure).

Avoid sending angry emails that you will regret.
Possible counterarguments against nudges.
Ban smoking, then alcohol, sex?
Sliding all the way down the slippery slope is unlikely, to be sure, but faced with the risk of overreaching, critics might think it is better to avoid starting to slide at all.
Choice architects may have their agendas.
Those who favour one default rule over another may do so because their own economic interest are at stake.
The invisible hand works best when products are simple and purchased frequently.
Skeptics might argue that in a free society, people have the right to be wrong, and it is sometimes helpful for us to make mistakes, since that is how we learn.
We insists on easy opt-out rights.
Children should not learn how to swim falling into ocean and hoping for the best.
Pedestrians in London should not be teach to look right by hitting them by a bus.
Is subliminal advertising good way of achieving libertarian paternalism? It doest steer people's choices, not making decisions for them. What limits should be places on private or public manipulations as such.
Drink more water, Don't drink and drive, Smoking kills, Support your president, Abortion is murder
Publicity principle – government are banned from selecting a policy that it would not be able or willing to defend publicly to its own citizens. The government should respect the people whom it governs and do not treat its citizens as tools for manipulation.
Neutrality is often thought to require randomness.
Why is randomising ballots good and randomizing assignment to insurance policies bad?
In some cases, forces choosing is best.
Should governments educate people about the risks of smoking, drinking ,unprotected sex, spike-heeled shoes?
When nudgers have expertise, and when differences in individual preferences can be easily estimated, then the potential for helpful nudging is high.
If we want to protect people, why not go further? Would it be best if wee took away freedom of choice at all?
Rule: Opting out has to be easy – "one-click away"
Asymmetric paternalism: Guiding principle that we should design policies that help the least sophisticated people while imposing the smallest possible costs on the most sophisticated.
Prevent human errors by cooling-off periods – any door-to-door sale must be accompanied by a written statement informing the buyer of his right to rescind the purchase within three days of the transaction.
Mandatory wanting period before divorce. Nudgers are aware that people might act in a way that they will regret – regulators do not block their choices, but do ensure a period for sober reflection.
Should be possible to trade individual workers right to safe work environment in return for a higher salary?
Seemingly small features of social situations can have massive effects on people's behavior – nudgers are everywhere, even if we do not see them.
Choice architecture, both good and bad, is pervasive and unavoidable, and it greatly affects or decisions.
Choice architects can preserve freedom of choice while also nudging people in directions that will improve their lives.
Society is too diverse, individuals are too creative, circumstances change too rapidly and government is too fallible to one-solution-fits-all.
