Select all that apply. You want to ethically use both scarcity bias and the bandwagon effect in your marketing. Which of the following are appropriate ways of doing so?

Ethical use of scarcity bias depends on accurate availability signals, not manufactured urgency. Real inventory information helps visitors understand limited supply without misleading them. Ethical use of the bandwagon effect depends on genuine social proof from real customer experiences. Testimonials and reviews work because they reflect actual satisfaction and reduce uncertainty. Both tactics support trust because the persuasive cue is based on truthful information.
