Our final keynote speaker at Behavioural Design Week 2021 was Baptiste Tougeron. As a Google Research Manager, he is responsible for ad effectiveness. During his session, he presented the most read whitepaper of Google worldwide: Decoding decisions. He talked about the messy decision process and how behavioural science can supercharge the attractiveness of brands. A must-see if you work in branding, marketing and advertising.

Behavioural Design Week: Baptiste Tougeron

Purchase decision-making is not a linear process. Between the purchase trigger and the purchase, customers are exposed to much information, like reviews or social media. The Google research team tried to uncover how customers process all this information and make decisions between the purchase trigger and the purchase itself. The call it “The messy middle”.

Baptiste Tougeron: Our key take-aways

Key-take away 1: Organise the messy middle:
Between the purchase trigger and the purchase, we can identify two ’mental modes’. The Exploration Mode and the Evaluation Mode.

While the Exploration Mode expands our consideration set, the Evaluation Mode narrows down our options. People oscillate through these two mental modes, repeating them as often as they need to make a purchase decision. These two mental processes can run simultaneously or apart, but they are two distinctive processes.

Key Take-Away 2: Supercharge the brand with cognitive biases
Now that there is some order in the messy middle, we need to know how shoppers process the information. During the process of Exploration and Evaluation, cognitive biases shape their behaviour and influence their choice. In the research, six cognitive biases are prioritised:

  1. The Power of Free
  2. Social Norms
  3. Authority Bias
  4. The Power of Now
  5. Category Heuristics
  6. Security Bias 

Important conclusions to keep in mind:

  • Ensure brand presence, simply showing up can impact customer decision making when they are exploring and evaluating. (This is called the Mere Exposure Effect)
  • Intelligently (and responsibly) employ behavioural science principles to influence the decision-making process
  • Close the gap between trigger and purchase.

Baptiste Tougeron: Quotes to remember

“Purchase decision-making is not a linear process”.

“I would like to think of the messy middle as a big spaghetti plate”.

“The cool thing about behavioural science, if you put the theory into practice in different countries, the brain remains to work very similarly.”

“We are not done. We still have to explore ‘exposure’ and ‘experience’, so lookout for new research and results in 2022”.

“Playing with the six cognitive biases is not easy. You cannot choose to supercharge your brand just like that. Some biases you can influence yourself, others need to be acquired”.

Want to learn how to apply behavioural science yourself?

Suppose you want to learn more about how influence works. In that case, you might want to consider joining our Behavioural Design Academy, our officially accredited educational institution that already trained 1500+ people from 45+ countries in applied Behavioural Design. Or book an in-company program or workshop for your team. In our top-notch training, we teach the Behavioural Design Method© and the Influence Framework©. Two powerful frames to make behavioural change happen in practice.

You can also hire SUE to help you to bring an innovative perspective on your product, service, policy or marketing. In a Behavioural Design Sprint, we help you shape choice and desired behaviours using a mix of behavioural psychology and creativity.

You can download the Academy brochure here, contact us here or subscribe to Behavioural Design Digest at the bottom of this page. This is our weekly newsletter in which we deconstruct how influence works in work, life and society.
