88 students were told about an exercise training camp and split into 2 groups: either having a choice about  the four fitness programs on offer or having one randomly assigned. They were then asked to rate their anticipated satisfaction of the program out of 9.

Those given some autonomy reported higher levels of anticipated satisfaction than those who weren’t.

Choice = autonomy = certainty. 

For instance, giving people a choice to still use the old version of your software platform for a given timeframe will reduce anxiety and uncertainty.

Product type matters.

‍People desire autonomy for pleasure purchases (i.e. vacations) more than for practical ones (i.e. business trips).

Place more focus on the former in order to maximise feelings of control and consumer satisfaction (Botti & McGill, 2011).

Change behavior with the ‘4As’.

Feeling that any change originated from within is vital.

‍Ask about the behavior, advise them impartially of the facts and of better routes, but that they must make their own choice.

If keen to change, assist them to make a commitment to do so by a given date, and arrange a follow-up to support this behavior change.

142 people were split into 3 groups and were shown either 72 nouns, abstract words or pictures on a projector for a split-second each, with 5-second pauses in between. They were then asked to recall as many items as possible.

Results showed that those in the picture group recalled far more than either word groups.

Boost your message.

‍Visual ads are remembered better in the long term than verbal ads, especially when we are under greater cognitive load (Childers and Houston, 1984).

What emotional message can you convey more powerfully with a striking, visual metaphor over mere words?

Boost learning by adding in visual references, and not relying solely on text-based language.

This can help broaden understanding across cultures and age ranges.

Where are you trying to change behavior?

What image do you want to stick in peoples’ heads to simplify understanding?

Make product choices distinct.

Images are internalized twice, both visually and verbally (see Dual Code Theory), so they stick in the brain better than just words.

This holds as long as the images aren't abstract or similar to one another (Reder et al, 2006).

So if you sell a large product range that looks similar, consider modifying their design or how they're presented to heighten relative differences and create a more distinct range of choices.

153 New York pedestrians were approached by someone dressed as either a civilian, a milkman or a police officer and were asked to help out a stranger by covering the cost of his / her parked car ticket.

The more authoritarian the uniform, the higher the chance they’d give the money. The civilian succeeded only 33% of the time, whereas the police officer managed 89%.

Determine an authority figure with relative expertise in relation to the group and behavior you’re looking to influence.

Ensure that the individual is credible and trustworthy.

Communicate their authority clearly.

For instance, using authority indicators like “Doctor,” “Judge,” “Award-winning” etc. Complementing this with a suitably-dressed photo of said individual will make any request much more effective.

Add a quotation too to bolster the effect, along with any extra reputational labels they might have (e.g. academic background, specialisms, career duration etc).

Compliance varies depending on demographics.

Older people are more compliant than younger people, for instance. For the young, use culturally-relevant aspirational models to mask authority whilst also nudging desired behavior.
