When you goto the grocery store, can you trust someone is vaccinated if he/she not wearing a mask?

Experts say many people will lie. That’s the problem without a vaccine passport or basic verification system.

CDC didn’t consider this problem enough. #COVID19

2) “The CDC's announcement Thursday that fully vaccinated people largely no longer need to wear a mask has left many Americans wondering: If there are no enforcement measures, won't people just lie about their vaccination status?

3) “Public health officials admitted that the honor system will play a large role in the new rules.
"I mean, you're going to be depending on people being honest enough to say whether they were vaccinated or not and responsible enough to be wearing ... a mask," said Anthony Fauci

4) There's long been talk of a "vaccine passport" model of enforcement, where vaccination status grants or limits ability to travel or enter certain spaces. But multiple businesses announced that they won't ask customers to prove their vaccine status if they shop unmasked.

5) Although businesses and politicians say they trust Americans to be honest, experts on human behavior aren't so sure.
Michael McCullough, a psychology professor at the UC San Diego, said the new guidance will enable unvaccinated people to flout rules with "impunity."

6) "Many will lie. Many are lying, have been lying. In some ways, this is a really perfect recipe for people to be dishonest about whether they got vaccinated. They can say, well, everyone who really is worried about it has gone out and done it, and my personal risk is low."

7) Most people lie about once a day, and about 25% of people lie about "consequential things," according to Michael Cunningham, a psychologist at the University of Louisville who has done 35 years of research on lying, cheating and stealing.

8) Many daily lies relate to the "expectation maintenance theory of lying," Cunningham said – trying to maintain cordial social relations by telling people what they want to hear.

9) "Most of the time, we don’t lie for malicious reasons," said Kang Lee, a professor at the University of Toronto who studies honesty and deception. "I don’t like to get you into trouble. We lie sometimes for pro-social reasons. I want to spare your feelings."
