TRUSTWORTHY SMILES

Summary from the TLDR Marketing newsletter

Using a genuine smile in a profile picture can increase approachability and reduce perceived risk, leading to more sales. Consistently using the same photo across platforms leverages Familiarity Bias, making people more likely to trust and choose you. Research shows people make judgments about trust in milliseconds based on facial cues like an upturned mouth and slightly raised eyebrows. One study found people invested up to 42% more in strangers with trustworthy features.
