The Goodvertising Agency along with the Danish unemployment fund Min A-kasse have conducted a social experiment to reveal how mistrust and mistreat influence people’s productivity and self-confidence, especially in regard to the unemployed.

Together, they’ve filmed a video with the identical twins Jesper and Anders passing an IQ test, where the latter performs 16% worse than his brother just because of a psychological discomfort he experiences as a result of mistrust from a tester.

This social experiment aims to raise people’s awareness not only in Denmark but across the world of how important it is to treat each other respectfully, especially those without a job who are more likely to feel inferior because of their social status.
