Nello: Ad Behaviour & Psychology

The psychology:This leverages the Open Loop Statement principle by creating a suspenseful, incomplete idea that triggers the brain's need for closure. The viewer experiences the Zeigarnik Effect, which makes them remember and focus on the unfinished information, increasing engagement and anticipation for the resolution.

The psychology:This leverages Authority Setup by explicitly referencing the speaker's favored adaptogen, signaling expertise and credibility. The personal endorsement activates Social Proof, as viewers infer that the speaker's preference is based on experience. Together, these principles increase trust and make the viewer more receptive to the message.

The psychology:This leverages the Principle of Specificity Bias by naming a concrete mineral, magnesium glycinate, and the common deficiency associated with it, which makes the information feel credible and urgent. It also uses Social Proof by implying that 'the majority of us' share this deficiency, creating a sense of shared experience that increases viewer engagement and trust.

The psychology:This leverages Metric Proof by providing specific, measurable data points that make the claim feel credible and verifiable. The specificity reduces ambiguity, triggering the Specificity Bias, which makes the information more trustworthy and easier for the brain to process. Together, these principles increase the viewer's confidence in the method's reliability and effectiveness, making them more likely to accept and remember the claim.

The psychology:This leverages the Cost/Benefit Shift by reframing stress reduction as yielding both life extension and physical appearance benefits, increasing perceived value. It also uses Specificity Bias by naming 'stress is the number one killer,' which concretizes the risk and heightens urgency. Together, these principles make the viewer reassess the benefits of stress management, motivating engagement through enhanced perceived payoff.

The psychology:This leverages the Hidden Problem principle by revealing an unseen factor—cortisol levels—that contributes to the viewer's challenges. It also uses the Curiosity Gap by prompting the viewer to wonder what happens after lowering cortisol, engaging their desire to understand the hidden cause-effect relationship. This combination makes the viewer more attentive and invested in the explanation that follows.

The psychology:This leverages the Specificity Bias by providing a clear, concrete statement that feels credible and actionable. It also uses Embodiment Effect, connecting the lesson directly to the viewer's body, which enhances memory retention and personal relevance. Finally, the Closure Principle is at play, giving the viewer a satisfying conclusion that wraps up the content neatly, increasing the likelihood they will remember and internalize the message.
