Becky is а dentаl hygiene student аnd is in a sоrоrity at the University оf Minnesota. Many of her sorority sisters are using charcoal toothpaste to whiten their teeth. However, Becky learned in her dental hygiene courses there is not robust evidence to support the safety or effectiveness of charcoal toothpaste. Despite her knowledge, Becky elects to use the same charcoal toothpaste of her sorority sisters. She decides to do this because she has observed her sorority sisters all have white teeth and do not seem to have any issues. Which model or theory best aligns with Becky’s decision?
