Pleasurable and delightful experiences are one of the top goals for any successful product. Products nowadays — and with the increasing awareness of the importance of the user experience — are aiming for more than usable and easy to use products.



Revolutionary products focus on the experiences of their users, how to make their product emotionally engaging, how to motivate their users and encourage them to use the product and how to create a value for users from using it.

In his book Seductive Interaction Design, Stephen P. Anderson introduced the user experience hierarchy of needs model, From bottom to top is a basic product maturity continuum: a top to bottom focus starts with the experience you want people to have.


Why Uncertainty Is Effective?

1- Uncertainty Boosts Motivation To Complete Tasks




Eighty-seven college students from the University of Chicago took part in a study. Their task was to drink 1.4 liters of water in 2 minutes for different cash rewards. There were two kinds of rewards: certain rewards and uncertain reward.

In the certain-reward condition, if the participants drank down the 1.4 liters they would receive $2. In the uncertain-reward condition, if the participants drank down to the indicated amount, they would receive a reward. The experimenter would then flip a coin to determine whether the reward would be $2 or $1.

70% of the participants in the uncertain-reward condition successfully completed the drinking task, whereas only 43% of the participants in the certain reward condition successfully completed the task.


2- Unexpected Rewards Releases Dopamine



When we are surprised or faced with an unexpected rewards, our brains releases dopamine. Dopamine is a neurotransmitter that helps control the brain’s reward and pleasure centers. Dopamine also helps regulate movement and emotional responses, and it enables us not only to see rewards, but to take action to move toward them.

When the rewards are predictable, we know accurately what we are going to get and our dopamine levels stay as it is. But when rewards are variable and unexpected, our brains release dopamine and we work for the next reward.

Dopamine do these to our bodies and brains:

  • Boost motivation
  • Feel more pleasure
  • Better learning
  • Increase attention and focus
  • Boost creativity
