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.

11k people were offered a new job that had a 50% chance of doubling income for life, but it wasn't without risk, with an equal chance of it falling by either 20, 33 or 50%. Questioning started with the 33% gamble; if people took it, they were asked if they’d take the bigger 50% gamble too. But if they didn’t, they were asked about the smaller 20% one.

Results put people into four risk categories showing the majority were not willing to take any risk at all.

Focus on an improvement metric. 

We prefer the certainty of what we’re used to, so the benefits of switching to a new product need to feel substantial.

Outline a goal (relative performance, efficiency etc.) to anchor your product strategy around.

Doing so will reduce uncertainty and boost comparisons against better-known, lower risk alternatives.

Offer a trial or free sample...

...to create familiarity and reduce the risk around a new product.

This sets the cost of new product usage at zero, during which the consumer will adjust their future preferences.

Utilize your brand umbrella.

For any new sub-brands, reduce risk by clearly indicating the relationship to existing, familiar brands you own (Erdem, 1998).  

Product brands take note. Risk aversion is higher for material purchases than for experiential ones such as restaurant meals or holidays (Roche et al., 2015).
