2 Section 1: Overview - What is Behind This Thing Called "Nudging"?
“Influence, Persuade, Nudge: Master the Science of Getting People to Take Action” Outcome This course is designed for those who wish to learn and practice a new and science-based approach (Nudging) to influence or persuade others to do what is best for them and their organizations. Nudging is a tool or technique that can be seamlessly incorporated into your current organizational efforts to change the behavior of others. It can also be used as a standalone performance improvement device. Mastering nudging will give you an inexpensive, scalable, and provable method to get people to take action.
Objectives Those who complete the course will: 1. Discover a new way to influence the behavior of employees (and clients)
2. Encounter the cognitive science behind nudging that resulted in a 2002 Nobel Prize
3. Determine which behaviors are most appropriate for a nudge
4. Practice a proven four-part method for crafting a powerful nudge
5. Use the method many times during the day to hone your nudging skills
6. See and experience a second method for maximizing the effects of nudging

3 What is nudging? At its simplest it is, “The science of getting people to take action.” Bri Williams, author of “Behavioral Economics for Business”
Would you like an alternative definition? “A nudge is a means of encouraging or guiding behavior, but without mandating, instructing… or using financial incentives or sanctions.” David Halpern, author of “Inside the Nudge Unit”
What does this have to do with me?
You can effectively use nudges with your colleagues, team members, direct reports, trainees, or clients. You can use nudges to influence or persuade them to:
• Meet a deadline(s).
• Do more of something you discussed and agreed upon.
• Do less of something you discussed and agreed upon.
• Embrace a difficult change you discussed and agreed upon.
• Be more regular in the habit of doing something.
• Take a step of an agreed upon assignment.
What is cognitive bias? (In plain English)
A bias is a tendency. Cognitive bias is something we are unaware of and happens outside of our control. It happens automatically and is triggered by our brain making quick judgments and assessments of people and situations, influenced by our background, cultural environment, and personal experiences.
Using an awareness of bias to build a nudge
We can use this awareness of bias in others to design ways to influence their behavior (nudges). In fact, nudge theory argues that this knowledge of bias can be used to persuade individuals without resorting to coercion, regulations, or enforcement.
Nudges are simple, inexpensive, science-base, and can be used in conjunction with existing approaches.

16 The EAST Model
The model seems so simple… What could possibly go wrong?
It seems like “common sense”, but is it? If common sense drove our behavior… • Savings • Diet • Exercise • Change Initiatives driven by our employer
Let’s go a bit deeper (three examples) Commitment/Consistency There is an OPTIMAL WAY(s)
Social Proofing There is a WRONG WAY
With every Nudge There is CONTEXT to consider

20 25+ Nudges using the E.A.S.T. Model
E - EASY
EASY – If you want to encourage a behavior, make it easy.
HARD (corollary) - If you want to discourage a behavior, make it hard.
• Modify the Environment o Cafeteria food, supermarket checkout – Make fruits and healthy choices easy to see and access. Make junk food difficult to access (high shelves for example). o Reduce the size of the dinner plate or bowl. This has been proven by lab and other practical experiments to assist in dieting. • Simplify letters, forms, and messaging to see marked increases in returns/responses. EXAMPLE / Save a click – A tax letter was changed to take people directly to a web link For a needed tax form (versus to a web site where they needed to search for the form and click to it). Result – a 22% increase in form completion.
• Make it harder to do something undesirable. In a federal government effort to save paper, a team designed an experiment to add a single extra step to print single-sided vs double-sided. They achieved a marked decrease in paper consumption.
• Checklists and Job Aids – What many of us consider simple checklist can be very powerful in changing behavior. They can reduce friction, make tasks easier, and assist in overcoming the status quo bias. More? See Atal Gawande’s “The Checklist Manifesto”.
• Substitution –Substitute cigarettes for E-cigarettes (looking increasingly like a poor substitute) or substitute sitting at your desk all day with standing occasionally.
• Chunking (creating goldilocks tasks) – Mihály Csíkszentmihályi (a famous behavioral scientist who has written extensively for business), says that we are motivated to obtain mastery and mastery comes by sticking to a task over time until we master it. We can maintain our motivation or the motivation of others by breaking complex tasks into chunks or “Goldilocks Tasks” (tasks that are not too easy but not too hard).
• Goal Setting – Setting goals results in better completion rates and better results. EXAMPLE / In one well-controlled experiment, marathoners who decided upon a pre-determined race goal (a finishing and associated split time or time per mile) had six minute faster times in the full marathon, than those who failed to set a pre-race goal. 21 A - ATTRACTIVE
ATTRACTIVE – If you want others to choose an option or adopt a new behavior, make it attractive.
UNATTRACTIVE (corollary) – If you don’t want people to choose the option of engage in a behavior, make it unattractive
• Framing Effect – we react differently depending on how information is framed o 3% fat vs 97% fat free (example from nudge Course) o Framed as a loss is more powerful than framing as a gain (see below) o Frame so that it is important to the person – how? WIIFM (What’s in it for me?) • Scarcity – When something is deemed to be scarce, it is more desirable or attractive to us. Limiting the time to sign up for a government program increased the rate of sign up. • Link an unattractive behavior to one that is attractive – For those who hate to exercise it can be made more attractive by linking it to a desirable activity. (An exercise session can become a walk in the woods or time at the gym can be reframed as a time to get together with a group of friends.) • Personalize – Personalize a letter – even a business letter, tax letter, etc.… o Adding a picture of the person or a handwritten note in a letter can boost overall tax payments, the timeliness of payments, and the percentage of fines paid. • Salience – Make your appeals new or novel. Add a handwritten note to envelope or letter or simply handwrite name and addresses. Add a personal note, congratulations, thanks, etc. to the letter (or email) for increased results. o Adding a stamp to the letter – Stamp said - Pay Now! This stamp resulted in a boost of 14-17% or a 10 million pound increase for a British traffic fine collection effort. o Another tax example can be found on page 89 of Inside the Nudge Unit. The tax letter and envelopes were personalized with a handwritten, “David, you really need to open this!” The experiment resulted in a responder vs non-responder rate rose from 21.8% to 26% It had a cost (the wages of the writers), but had a 200:1 ROI! • Loss Aversion – It is an extremely strong bias that was illustrated many times during the nudge class. This was one of the first heuristics explored by Kahneman, author of Thinking Fast and Slow and winner of the 2002 Nobel Prize in Economics. • Endowment Effect - If you are given something, even something you don’t particularly want, and then asked to return it, you are reluctant to do so. If you are given something that has a worth of $3.00, you will be reluctant to sell it or trade for a similar item unless offered at least twice what the item is worth. (Related to loss aversion, this bias has been proven in many lab experiments). • Related to the endowment effect is the Ikea Effect. If you build something, even if your product is substandard, you will value it beyond its intrinsic worth.
22
S - SOCIAL
SOCIAL – We are social beings who use other people’s behavior to as a cue for our own behavior. If you want others to take action, link those desirable behaviors with social factors or social interaction.
• Social Proofing or Descriptive Norm – We use other people’s behavior to as a cue for ourselves. Apply this by reminding people that others are “doing the right thing” and how many of them exist. Avoid pointing out those who are doing the wrong thing. The WRONG WAY to frame a message socially - The MDs office that says 25% of our patients are not showing up for appointments, nor are they calling to cancel their appointments. This results in MORE no-shows and less cancellations in advance, not less. Instead REFRAME the message the RIGHT WAY to - “Valued patients, Did you know that 75% of our patients show up on time and call in if they want to cancel. We hope you can join this group of valued patients!” Thank You! Dr. Goodnudge and Team. This sort of positive social framing has been proven to drive cancellations down. The border guard example was mentioned in the Nudge course today. When announced that a small group of border guards were selling favors illegally, illegal behavior rose! Again, reframe using the positive behavior you want to encourage and not the negative behavior!
• Relative ranking To drive down over-prescription of antibiotics, high prescribing MDs were made aware that fully 80% of antibiotic prescribers in their area prescribed LESS antibiotics than them. (i.e. they were in top 20% of prescribers) This had a significant effect on reducing their antibiotic prescriptions. Consumers of water and electricity were told 70% of their neighbors used less water or electricity than them. (i.e. they were in top 30%) This had a significant effect on their usage.
• Commitment Effect – Commitment has a huge impact on follow-through. Whether the commitment is oral or in writing, we tend to deliver on what we commit to. Consider combining commitment with other nudges such as: 1) specific goals – SMART goals for example, or 2) social proofing - by dieting as a group and holding each other accountable, 3) a loss - by asking everyone (upfront) to commit to losing a $50 ante to a charity they do NOT wish to contribute to (such as a non-preferred political organization).
• Feedback – Regular, positive, and constructive feedback gets good results (coaching, regular check-ins,...), as opposed to the “annual performance review”.
• Reciprocity – We are inclined to return a favor when we have received one (or something) from someone else. o Gift from a not for profit – small item boosts giving (address labels and such) 23
T – TIMELY
TIMELY – Timing Matters! See many examples below of how to use this bias to get people to take action.
Present Bias - We disproportionally prefer rewards that come now and costs that come later. A famous example is the “Save more Tomorrow” (Schlomo Benartzi and Richard Thaler’s program) from the video in today’s class. Their message is to save more for your retirement, but that one does not need to sacrifice today in order to save. One saves by committing now to take a percentage of any salary increases (a default decision in the future) that is deducted and invested automatically.
Prompts – Prompts can be effective, but they need to come at the right time. • Students were prompted via text in the summer, about the need to complete some forms in order to start community college in the fall. These text prompts proved successful in reducing “summer melt” or students that committed to college at HS graduation, but tended to “melt away” by fall. • Asking people in the process of writing their wills if they would be willing to donate to a charity increased the percentage of their giving. Again, the ask was at the right time.
Implementation Intention – This technique prompts people to commit to something (with detail) and often to do it on the following date and place. Proven experiments included: • Asking people if they intended to vote, when, and where. This increased those who actually voted. • Asking people to write down the time and place they were going to get a flu shot increased the likelihood they would get a flu shot.
Priming – Actions can be influenced by unconscious cues delivered at the right time. o A study found those primed with rude words were more likely to interrupt an investigator than those primed with neutral words. (Those primed with polite words were the least likely to interrupt.) • A Yale study showed that something as simple as holding a hot or cold beverage before an interview could result in pleasant or negative opinion of the interviewer.
Deadlines – people respond to deadlines • Cards or offers with expiration dates are used more than those without an indicated date.
Head start (endowed progress effect) People given a “head-start” toward a goal are more likely to finish a task. Example – A coffee shop loyalty card. A card with 12 holes (but two “pre-stamped” to give users a “head-start”) is used at a higher percentage rate than a card with 10 unstamped boxes. People respond not only to proximity towards a goal but also to “perceived progress”.
Peak End Rule – If you have a relatively difficult or unpleasant extended task or set of tasks for employees, design it to end on a positive note or experience. This last experience (peak-end) is what people tend to remember. (The tend to forget that which came before, even if difficult or unpleasant) 24 Building an EAST Square Need some assistance with nudges? • Easy (Remember there are lots of nudge ideas on page 21) • Attractive (Remember the nudge ideas on page 22) • Social (Remember there are lots of nudge ideas on page 23) • Timely (Remember there are lots of nudge ideas on page 24) Advice • Start by generating a “good behavior” to nudge (the center square). Not too big, not vague, but clear, definable, measurable, and doable. (Remember SMART) • Try to generate at least one nudge for each letter in the EAST model first • Then see if there are additional nudges for a specific letter of the E.A.S. T. model. In the example below (the SETA example) there are probably multiple ways to make this task of communicating more regularly or consistently more S- Social or A-Attractive.
Remember our SETA example and how we construct an EAST Square?

This reinforced the lesson(s) on:
I never would have considered the following:
Do you think sales-people use any of these techniques? What should you be aware of with sales-people?
Who else is trying to influence you?
Can you protect yourself? How?

27 Section 5: Testing Your Nudges
Do you test or measure your attempts to change behavior or get people to take action now?
Why or why not?
When might you want to consider testing (or measuring your nudges)?
How might you go about it?
28
A/B Testing A/B testing is also known as split testing. It is simply a method of comparing one approach (one training intervention or nudge) versus another approach or no approach (a control group). A/B testing is essentially an experiment where two or more variants are used with two audiences. Some basic statistical analysis is then employed to determine if there is a statistically significant variation between the two outcomes. Care should be taken to test only one variable at a time.
More on Experimentation and Measurement Many of us in the workplace are reluctant to experiment and publicly measure the efficacy of different tools and techniques. We believe that we should work on our design and methods until it has reached “perfection” and then roll out our product or service.
This is not how most modern software and technology is developed. Most current models are “agile” or use a “lean startup model’. These models encourage developers to build, measure, and learn in a constant repeating loop on the way to improving the product. Nudges are an ideal candidate for this agile approach. New nudges could be rolled out monthly with any number of your current workplace efforts and measured independently.
Of course, you can nudge without any measurement at all. Some nudges may simply make sense and be accepted by management and participants. But if you want to scale up your efforts and have proven results to take to management, it is always best to test or measure.
Nudges are based on solid empirical findings from the social and behavioral sciences. Why not reinforce the validity of this approach by STARTING with good science and ENDING with good science? This can be done by rigorously testing your results.
29 BONUS PAGE
Are there ethical (or non-ethical) ways of nudging? Yes. See Richard Thaler’s Three Rules of Ethical Nudging Below
The Ethics of Nudging – an academic article from Harvard’s Shared Abstracts https://dash.harvard.edu/bitstream/handle/1/16151743/ethics11_20a_2.pdf?sequence=1
A New York Times article “The Power of Nudges for Good and Bad” (a short and succinct look at the ethics of nudging by Richard Thaler) https://www.nytimes.com/2015/11/01/.../the-power-of-nudges-for-good-and-bad.html?...
Seven Ways to Use Commitment to Nudge: 1) Start with a small commitment and then ask for more commitments or stronger ones. 2) An oral commitment (even to ourselves) is stronger than a silent commitment. 3) A written commitment is stronger still. 4) The timing of a commitment can matter. Research has shown that a signature (commitment) at the top of a form can have more effect than a commitment at the bottom of a page. 5) A social commitment (social media, announcement to a peer group, etc.) can increase the likelihood of following through with the commitment. 6) A commitment to do something we don’t like or where we stand to lose (loss aversion) increases the likelihood of follow-through. (For example: It has been found that pledging to give money to a cause one loathe, if we fail to lose weight or exercise, can increase the likelihood to sticking with a task or goal.) 7) Combine commitments with other nudges. Commitments tied to specific goals (S.M.A.R.T. Goals for example) can increase the likelihood of following through with the commitment.
