You think expressing emotion online makes your message land harder. The research says the opposite is happening. A 2026 Cornell study found that emotional posts, whether text, simulated news, or video, don't just fail to persuade; they actively damage your credibility with anyone who doesn't already agree with you. Understanding why changes how you communicate in every high-stakes context.

Here's what Cole and Phil break down in this episode:

• Andrews, Olson, and Koff (Cornell, 2026) — six pre-registered experiments, 6,400+ participants testing emotional posts across social media formats

• The sincerity alarm: how the brain runs a background appraisal of whether emotion is genuine or performed
• Why TikTok-style video produces the highest skepticism response of all three formats tested
• The critical distinction between making your audience feel something versus displaying your own emotion to them
• Brady's research on moral-emotional language and how platform algorithms have recalibrated audiences toward cynicism
• The empathy gate: why emotional contagion depends on perceived authenticity and what closes it
• Emotional posting as a cohesion mechanism, not a persuasion mechanism, and why most people are using the wrong tool for the goal they actually have
• Practical implications for leaders communicating layoffs, reorgs, or failure across different media
