The Bizarreness Effect

The Bizarreness Effect

We tend to remember unusual, bizarre, or distinctive information more easily than ordinary information. This bias reflects the impact of novelty on our memory retention.

The study of the Bizarreness Effect can be traced back to the early days of cognitive psychology in the mid-20th century. But it wasn’t until the 1970s that researchers started investigating it more thoroughly. Craik and Tulving’s 1975 study found that people better recognized words presented in unusual contexts compared to ordinary ones. This laid the groundwork for further exploration.

In the 1980s, McDaniel and Einstein’s experiments solidified the Bizarreness Effect as a robust psychological phenomenon. They showed that bizarre information improved both recognition and free recall of information.

The 1990s and early 2000s focused on understanding the mechanisms behind the effect. Hunt and Worthen proposed that the distinctiveness of bizarre information was key to its memorability, arguing that it stood out against ordinary details.

Recent neuroscientific studies using fMRI have shown that processing bizarre information activates brain areas associated with novelty detection and memory formation more strongly than ordinary information does.


In the context of team dynamics, the Bizarreness Effect has many implications on how our teams operate, innovate, and grow.

Understanding this effect is important for leaders in shaping culture and communication strategies. Slightly unconventional messages can make visions and values more memorable, but too much bizarreness can confuse or distract from the core message.

The effect impacts how organizations approach innovation. Encouraging unconventional thinking can lead to memorable, groundbreaking ideas. However, leaders should also be careful not to overlook effective conventional solutions!

Incorporating unusual elements into training programs could enhance retention and engagement in learning and development. For example, using unexpected analogies might help employees remember key concepts better.

Lastly, presenting ideas in slightly unconventional ways can make messages more engaging in change management. However, changes might face resistance if they’re perceived as too bizarre.

🎯 Here are some key takeaways:

Be aware of the bias towards the unusual

Your team might naturally remember and talk more about strange ideas than normal ones. Try to give all ideas a fair chance, no matter how ordinary or unusual they seem.

This can effect employee reviews

The Bizarreness Effect can influence performance evaluations, potentially favoring employees with unusual approaches. This might unintentionally bias against consistently good performers with less attention-grabbing styles.

Employ the "pattern interrupt"

In long talks, throw in something unexpected now and then. This could be changing your tone, asking a surprise question, or giving a weird example. These changes can wake up your audience and help them remember what you're saying.

Make sure everyone gets a chance

Remember that this effect might make people with unusual ideas stand out more. Make an effort to let all team members share their thoughts, whether their ideas are out-of-the-box or more traditional.

Keep things balanced

While adding surprising bits can be effective, don't go overboard. Make sure these unusual parts help explain your main points, not confuse people. Always keep your core message clear and easy to understand.
