Crowdfunders would be wise to listen to Jessica Li, a Kentucky University assistant professor of marketing in the School of Business, whose study focused on just how wide your smile should be in your crowdfunding photo.
As it turns out, not too wide.
The study found that “”broad smiles lead people to be perceived as warmer but less competent,” For all you startup entrepreneurs out there, “photos with a slight smile did better in marketing scenarios where services were higher risk…More people wanted to donate to their project because they believe this competent person is able to deliver the product.”
