What are heuristics?  

 

  • Discission strategies
  • Rules of thumb
  • Intuitive judgement
  • Educated guesses
  • Automotive choices

 

We have a trigger and then a whole sequent that is taking place to get you to make your discission or behavior.  They are highly efficient. Can help us because we have limited cognition. We have limited energy and time to deliberate every choose we have to make. Also they are mostly correct, they give us the right answer. Sometimes it leads to unwanted behavior.

 

Interesting heuristic:

 

  • Look at people that were in line for a copy machine. The people wanted to go first.
  • Control: Excuse me, I have 5 pages, can I use the copy machine? (60% went along)
  • Condition: Excuse me, I have 5 pages, can I use the copy machine? Because I’m in a hurry (94% went along) (the reason you’re giving is giving more information)
  • 2nd condition: Excuse me, I have 5 pages, can I use the copy machine? Because I have to make some copies. (93% went along) (the reason you’re providing does not give you any more information) It’s the because that is triggering the script.
  • Again control: Excuse me, I have 20 pages, can I use the copy machine?
  • Condition: Excuse me, I have 20 pages, can I use the copy machine? Because I have to make some copies. (go along in same rate as no-reason condition/ control group)
  • 2nd condition: Excuse me, I have 20 pages, can I use the copy machine? Because I’m in a hurry

 

How raising the price can actually increase sales

 

When you see two products you probably assume that the one with the highest price is better. We often use price as a heuristic to determine the quality of a product. It will also influence your taste. Image a gathering with friends and you buy an 11eu bottle of wine. You really can taste that it tastes nice. Experiment with beer: people drank the same beer, only the price was different. People tend to think the more expensive beer was tastier. When a product is free, people will rate it as less valuable. Complimentary goods (free bracelet when having subscription journal).

‘How much are you willing to pay for this bracelet?‘ People that have the information that the bracelet is a complimentary good are willing to pay 35% less.

 

Discounts are effective. People will still rate the product as highly valuable. Even when there are no real savings, makes that people are more willing to buy that specific product.

 

 

Why and how to ‘play hard to get’

 

Money that come easily is different spent than money you worked hard for. If it is hard labored you spent it on rational things such as groceries. Easy money you spent on easy things like toy cars. Effort is often used as heuristic to indicate how vulnerable something is.

 

For your relationship: when somebody plays hard to get you are looking back at all the effort you put in. Assuming you like this person very much, because I did all those things for them. It is in hindsight. If it is in foresight: looking at what effort you have to put in. Thinking about 12 nice things about your boyfriend/girlfriend is really hard. The effort that is involved in getting to these 12 things is; maybe I don’t like this person this much.

 

Effort is also an effective effect when you have to think about arguments. If it is hard to follow an argument it is less likely to be seen as true. Think about rhyme; this works because it is easy to progress.

 

If your handwriting is very slopy that automatically the argument that you write down less persuasive. The same is true for how you build up your sentence. People take the effort that is put in the progress of the argument as an indicator of quality.

 

Simulation, recognition and similarity as weapon of influence

 

Familiar heuristic: many people, when giving them two options, rate the option that is familiar to them as higher than the other option. Something that we recognize is often chosen.

 

Similarity heuristic: when making judgement we often compare the current situation to other situations. When we have negative experiences, we try to stay away from experiences that looks like the other one. The same is hold for positive experiences.

 

Simulation heuristic: the way we can imagine something. Risk analyses. The risk of dying in a plane crash and the rate of dying of an overripe avocado. If you have to choose you obviously choose for the plane crash because you see this in movies and therefore are more known.

 

Imagine: you must take the train and you are in a hurry. You see that the train is long gone / you see that the train is just leaving. You feel more regret in option B, because you can imagine that if some little thing went faster, you could have catch the train.

 

The product made to influence you

 

When we make judgements, we often use referent points. What we use as referent point will influence our judgement. When we use a smurf you will see Kees as a giant person. But when you use a basketball player you will see Kes

es as a little person.

 

Price: if you first offer a product for a high price, and then offer additional good as less expensive. The price seems even lower. E.g. when selling a car they sell you the car for high money. Then you get accessories such as leather things.

Contrast principle: first make sell for expensive product and then come up with additional aspects.

Real estate agents: first let you see an expensive house that is not nice. The next house that are shown look automatically nicer and you buy them faster.

 

Adding alternatives

 

When comparing to referent points some options looks nice and some won’t. Lets assume you want to save money in the bank. There are two options you can chose.

A: 3,2% savings over 5years

B: 3,4% savings over 10years

There are only a few people who chose option B. The bank want to increase this by adding another option.

C: 3,45% savings over 15years

Now option B looks really good, and more people will choose this.

 

Compromise

 

First date in a restaurant. You have a great meal and want a nice wine to accompany this. On the menu:

no 1: very expensive.

Middle option: less expensive.

Last 1: carton box wine

Most likely people will go to the middle one. They like the affordable option, but having the middle one you compromise. You expect a little more, but you also pay a little more.

Coffee with cows

 

Your inner cow --> social proof / social norms. Powerful.

 

An introduction to social proof

 

All about being packed of other people to your behaviour/beliefs. It is so powerful that we wear ugly shoes (UGGS), because everybody is wearing them.

 

Conformity, experiment of Shirive and Ash. Other links will show this.

 

We even are influenced by people, when it goes clearly against our own judgement (not only when we have no clue, so we follow the rest).

 

Two processes of conformity

  1. Normative social influence: we act in line because we want to be liked.
  2. Informational social influence: you want to be correct in your judgment; say so because everyone says so, because you think they will know what’s right. (observational learning)

 

Social norms

 

Based on conformity. Social norms are what kind of behavior in society/setting is accepted and what is not.

 

Different social norms

  • Injected social norm: the behavior perceived to be commonly (dis)approved. Mostly there is no spoken rule, but everyone knows it.
  • Descriptive social norm: the behavior perceived common. If a lot of people are acting a certain way, you are more likely to also act this way (this is probably the most correct wat to act, the most adaptive).

They can be both present in a given situation, but are in conflict. So.. What influence your acting in a situation? It is all up to salience. The extent to what type of social norm is most important.

 

Using social norms

 

Hotel has experiment where they manipulate the doorhanger that says to reuse your towel.

Hotel towel reuse (N= 260 rooms)

 

 “Help the hotel save energy," focusing on the benefit to the hotel. (20%)

 "Help save the environment," emphasizing environmental protection. (31%)

"Help save resources for future generations," highlighting the benefit to future generations. (31%)

"Join your fellow citizens in helping to save the environment," focusing on the descriptive norm (41%)

 

Curbside recycling

Field experiment with 600 households for 8 weeks

 

3 groups:

1. Information only

2. No treatment control,

3. Descriptive normative feedback (inform what neighbors are doing)

 

Baseline (4 weeks), intervention (4 weeks), follow-up (4 weeks)

 

Trying to reduce air-conditioning in California

It helps the most when you see your neighbor has a lower energy rate than you. Social prove is very influential in itself, the beauty is that we don’t acknowledge it. We are not accepting it.

Combined control is not doing anything at all.

Commitment and consistency

  • Cognitive dissonance
  • Self-perception
  • Social norm
  • Self-persuasion

 

Question

  • Dice game
  • Make a bet: what number?
  • How confident are you about your bet? (5-point-likert scale)

 

Self-persuasion

  • We are more confident about our chances of winning AFTER placing a bet than immediately before laying down a bet
  • Convince our self we have made the right choice and feel better about the choice (self-persuasion)   
  • More satisfied about purchases when you have made your decision
    • Products have more favorable and less unfavorable aspects when choices have been made
  • Minimalize regret
  • With which question can you increase voting by 20% ? Do you expect to vote? (yes = social desirable)

 

Cognitive dissonance

  • Discrepancy between beliefs and behavior causes psychological tension (cognitive dissonance)
  • Motivated to reduce the discrepancy
  • Changing beliefs or behavior
  • After a (behavior) choice has been made: we fool ourselves to keep our belief consistent with what we have already done or decided: rationalize decision

 

Theory of self-concept maintenance

  • A gain at the expense of honest self-concept
  • Try to avoid negative update of self-concept: when starts this?
  • What influences whether we update?

 

Negative update?

  • Categorizing: act as less dishonest
    • E.g. taking €1,- VS a pen
    • Malleability (extent to which you can reinterpret: pen is borrowing, money is stealing)
    • Limit (severity of dishonest behavior: taking someone’s life is bad bc you cant give it back)
  • Attention to (own) moral standards
    • Internal awereness
    • Salience of moral standard, personal norms

 

Attention to moral standards

  • 229 students
  • Solve set of puzzles
  • €10,- per solved puzzle
  • X
  • Manipulation
    • Recall books
    • Recall 10 commandments

 

    • Control (experimenter checks answers)
    • Recycle (take work sheet, report correct answers on paper)

If you set a person in front of the mirror they get more focused on their own personal norms

 

Self awareness

  • Making personal norms more salient
  • Ciadini et al.
  • People are more inline with personal norm in front of a mirror
  • In crime places there are placed a lot of mirrors: not only to see your personal norms, but also the idea that many people are able to see you.
