Psychological Biases in MrBeast Videos (Explained)

MrBeast, a well-known figure on YouTube, masterfully employs psychological tactics to draw viewers into his content.

Inhis videos, he frequently leverages Input Bias, Costly Signaling, and the Curiosity Gap, especially evident in titles and thumbnails.

Input Bias

Input Bias plays a big role in his strategy. This bias pertains to the human tendency to favor information that aligns with existing beliefs or knowledge. MrBeast crafts video titles and thumbnails that resonate with widespread desires or beliefs. For example, by showcasing extreme acts of generosity or unique challenges, he taps into the audience’s preexisting notions of heroism and adventure, making his content irresistibly clickable.

Costly Signaling

Costly Signaling is another potent tool in his arsenal. This concept originates from evolutionary biology, suggesting that individuals perform certain behaviors to signal valuable traits to others. MrBeast’s videos often feature him giving away large sums of money or expensive items, which serves as a signal of his resources and generosity. This not only boosts his social standing but also makes the content more attractive and trustworthy to viewers.

Curiosity Gap

Lastly, the Curiosity Gap is a technique where content creators provide just enough information to pique interest without satisfying it, compelling the audience to watch the video. MrBeast is a master of creating titles and thumbnails that make viewers curious about the outcome. For instance, a video titled “I Gave My 40,000,000th Subscriber 40 Cars” immediately sparks questions like “Who won the cars?” and “How did they react?” This gap between known and unknown drives viewers to click and watch.
