Whether it’s a diplomatic engagement or just a family holiday, eating together can go a long way toward getting people on the same wavelength. One study looked at whether eating similar foods actually has an effect on how well we collaborate (Woolley & Fishbach, 2017). In a mock strike negotiation, participants were given roles as either managers or union leaders and told to negotiate an hourly wage for workers; the dependent variable was the number of strike days until a deal was reached. At the same time, participants were given a taste test. In a slight variation of the actual study, imagine that participants were given foods that ranged from very different to very similar on a rating scale. Might the similarity of foods affect how people negotiate? (The researchers found that increased similarity of foods predicted a lower number of strike days.) What statistical test would you use?
