205 people were shown a description of a digital camera printed in a font that was either easy to read (high fluency) or hard (low fluency).
Results found that when easy to read, only 56% delayed choosing the camera, next to 71% when hard. Why? Fluency breeds familiarity, which we value greatly, because it’s unlikely to be harmful (Zajonc, 1968).
Keep it short. Whether for marketing, nudges or political persuading, low syllable, easy-to-conceptualize slogans will feel dramatically more intuitive for consumers. Next to a competing message, they’ll believe the one that’s easier to understand (Schooler & Hertwig, 2005).
Repeat. Repeat. Repeat. The mere act of repeating your message will increase its familiarity, which itself increases the extent to which it’s seen as true (Reber & Schwarz, 1999). Keep it consistent across your team and put it everywhere.
Keep product benefits concise. Consumers actually like a product less the more positive traits they bring to mind (Menon & Raghubir, 2003). This is because they start to associate your product with greater complexity and lower fluency.
100 people were split into groups and shown a list of sayings about human behavior that either rhymed or didn’t (e.g. “Woes unite foes” or “Fools live poor to die rich”). They were then asked how accurate the sayings were.
Those in the rhyming group believed their sayings to be more true than those in the non-rhyming group.
A little play to make them pay.
Where can you use rhymes to heighten belief and persuade in a playful way?
Combine with the Humor Effect and a short jingle for an extra boost.
Repeat to defeat.
Fluency Shortcut says that short, easy-to-understand sentences are believed and repeated more.
Where can you use short rhymes to speed up familiarity of new ideas and create memorable vocal repeatability?
Localize to vocalize.
Consider the 1970s ad in the UK by vacuum manufacturer Electrolux. Though the claim might have been true, 'to suck' more isn't always a good thing.
However, the negative meaning hadn't yet entered British English, so rhymes can be crimes, but only in certain climes!
249 supermarket customers were invited to one of two tables, displaying either 24 jams or 6 jams. They were then asked how attractive the jams were and observed as to whether they bought one.
The results found that though customers considered the 24 jams more attractive, they were far more likely to buy when there were only 6 jams to choose from.
Reduce choice difficulty. If customers are time-poor, reduce the number of dimensions along which your products are compared. Present choices in an organised, non-random order, especially with visual layouts.
Tidy up choice relationships. Highlight one dominant option, align the attributes along which products are compared, and eliminate products from your range that overly complement each other to decrease deferral and increase purchase likelihood.
Adapt to product expertise. Who is your audience? To what extent can they weigh up the benefits of each possible choice? Experts prefer more choice and the lesser-informed crave less.
Build around intent & focus. Intent: are they buying or merely browsing? If browsing, they’re not making a decision, and are less likely to feel overloaded. Focus: a single purchase or a bundle? Bundlers want more options, but Singles want fewer.
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.
32 dog-phobic children were split into 3 groups and shown 8 videos of either one child playing with a dog, many children with different dogs or no dogs, and then asked to interact with a dog themselves.
Those who watched another child play with a dog performed far better. Those who watched many children also kept this up a month later.
Provide mental shortcuts through the judgements of others; the more people, the more persuasive. First-time consumers of your product will benefit the most from this approach.
Persuade with similarity. We're most influenced by those who we deem similar to ourselves. Communicate characteristics relevant to that segment, such as proximity, gender / age, profession or social class to successfully direct behavior.
Use role-models. Understand the emotional drivers of your audience and seek out positive, aspirational individuals to direct specific consumer decisions and reinforce behaviors.
72 people were split into 3 groups: Humor, Neutral or Contentment and shown a respective video: Mr Bean (a British comedy show), an educational video or a beach scene. They were then all asked to solve a secretly-impossible puzzle.
Those humored spent 50% more time and made 2x moreattempts trying to solve the problem than others.
Make it funny. Consumers have more positive attitudes towards humorous ads and their brands, increasing intentions to buy (Eisend, 2008). However, levels are dictated by product category and how related the humor is to the product.
Funny stories are more memorable than other positive emotions like admiration or respect. Puns are particularly memorable because they force us to simplify our humor delivery to a single line, reducing mental effort (Summerfelt et al., 2010).
Bring humor into the workplace. It helps boost employee satisfaction (Decker 1987), leads to higher productivity (Avolio et al. 1999) and boosts creativity (Brotherton 1996). Ben & Jerry’s, Southwest Airlines and Sun Microsystems are well-known for their use of humor within organizational culture (Barbour, 1998).
47 subjects were given around 20 small, manual tasks to complete, one at a time. Experimenters randomly interrupted completion of half of these tasks. After, subjects were asked to recall as many tasks as possible.
There was a 90% higher recall of incomplete and interrupted tasks than those completed.
Make important task completion frictionless. If customers leave your site without finishing their order, make it effortlessly easy to get that completion feeling, such as allowing for completion with a single click, tap or swipe.
Focus on completion’s emotional release. Providing reward incentives for task completion actually demotivates consumers. Instead, remind them not just of the product they’ve not yet bought, but of the feelings that this ‘purchase task’ will unlock.
Make known campaigns incomplete and interactive. Greater familiarity with an advert increases consumer ability to complete an interrupted ad message. Active participation also boosts ad memory (Heller, 1956). So if your popular campaign’s reaching its end, consider a special second follow-up version that allows for active participation in completing the ad message.
