IKEA EFFECT BIAS

Ikea Effect Bias describes the tendency of people to place a higher value on products they have partially created or assembled themselves. This phenomenon is named after the Swedish furniture retailer Ikea, known for selling furniture in flat-pack kits that customers must assemble at home.

he IKEA effect was identified and named by Michael Norton of Harvard Business School, Daniel Mochon of Yale University and colleague Dan Ariely PhD of Duke University, who published the results of three studies in 2011. They described the IKEA effect as “labor alone can be sufficient to induce greater liking for the fruits of one’s labor: even constructing a standardized bureau, an arduous, solitary task, can lead people to overvalue their (often poorly constructed) creations.”

Example: A prospect is more likely to pursue his/her own financial plan than that one from an informed financial planner, CPA or professional advisor.

2011 study found that subjects were willing to pay 63% more for furniture they had assembled themselves than for equivalent pre-assembled items.

IN FINANCE AND INVESTING

The IKEA effect can contribute to reducing panic selling. Investors typically reduce their stock market exposure after a financial crash which often results in “buy high, sell low” strategy that is detrimental to long-run wealth accumulation.

Ashtiani et al.’s study proposes a nudge utilizing the IKEA effect to counteract this phenomenon: “actively involving investors in the selection process of the risky investments, while restricting their selections in a way that preserves a large degree of diversification.”

Kentucky-based healthcare provider Norton Healthcare has confirmed that it has suffered a significant ransomware attack that may have put the data of millions of its patients at risk. In a filing to the Maine Attorney General on December 8th, the healthcare giant said that 2.5 million individuals had been affected by the breach.

Meanwhile, the nation’s largest pharmacy chains have handed over Americans’ prescription records to police and government investigators without a warrant, a congressional investigation found, raising concerns about threats to medical privacy. Though some of the chains require their lawyers to review law enforcement requests, three of the largest — CVS Health, Kroger and Rite Aid, with a combined 60,000 locations nationwide — said they allow pharmacy staff members to hand over customers’ medical records in the store.

The policy was revealed in a letter sent to Xavier Becerra, the secretary of the Department of Health and Human Services, by Sen. Ron Wyden (D-Ore.) and Reps. Pramila Jayapal (D-Wash.) and Sara Jacobs (D-Calif.).

HIPAA anyone?
