Nothing to Declare

January 23, 2014

Professionals – such as doctors, lawyers, and financial advisors – face conflicts of interest (COIs) when they have a personal, and often financial, interest in giving biased advice. Requiring COI disclosure has become a popular way to try and protect consumers from biased advice, but previous research has shown that mandatory disclosures have little impact on advice recipients, and may even lead advisors to give more biased advice. However, virtually all of the prior studies questioned the effectiveness of COI disclosures that advisors were unable to avoid.

New research from Sunita Sah at Georgetown University’s McDonough School of Business and George Loewenstein at Carnegie Mellon University examines situations in which advisors have the ability to reject COIs – such as doctors who can decide whether to meet with and accept gifts from pharmaceutical companies. Published in Psychological Science, Sah and Loewenstein found that when COIs can be avoided, disclosure successfully deters advisors from accepting COIs so that they have nothing to disclose except the absence of conflicts.

Sah, lead author of the study and assistant professor of strategy, economics, ethics, and public policy at Georgetown McDonough, commented, “Prior research has cast doubt as to the effectiveness of disclosure for managing conflicts of interest, particularly when consumers have the burden of interpreting and reacting to the information. Our findings suggest that disclosure can become a successful intervention to managing some conflicts of interest if it motivates professionals or providers to avoid such conflicts.” 

Sah added, “Stating that you have no conflicts of interest or ‘nothing to declare’ can be a signal of quality or integrity to regulators and consumers which could be viewed as a competitive advantage. The ability for disclosure to change the behavior of providers in a positive way is advantageous, as it avoids relying on consumers to make use of disclosure information.”

For the study, the researchers conducted three experiments to determine how COIs influence advisors. In the first experiment, 97 advisor–advisee pairs participated in an online game with Amazon.com gift cards at stake. Advisors advised the advisees on the number of filled dots on a grid. Estimators were paid based on their accuracy, but advisors had a conflict; they were paid more if advisees gave an estimate that was higher than the true value. The set up – with advisees only seeing a small subset of the complete grid – was designed to simulate a situation in which a consumer receives advice from a better-informed, but conflicted professional. The results replicated previous research and showed that disclosure led advisors to give higher (and more biased) recommendations than nondisclosure.

In the second experiment, the researchers again randomly assigned pairs of advisees and conflicted advisors to conditions in which the conflict was either disclosed or not disclosed. There was, however, an important change from the first study: advisors were given a choice of whether to accept or reject the COI. Without disclosure, a majority of advisors (63 percent) chose the incentives that created a COI, but with disclosure a minority (33 percent) accepted the conflict.  Advice was higher (and more biased) for those who chose conflicted incentives than for those who did not, and, advisors in the disclosure condition gave significantly less biased advice than those in the nondisclosure condition. When advisors could eschew a conflict, disclosure encouraged them to do so.

Finally, in a study with 248 participants, the researchers added a third condition to the second experiment: voluntary disclosure.  In this third condition advisors decided both whether to choose incentives that entailed a conflict and whether to disclose whether they were conflicted. Similar to mandatory disclosure, voluntary disclosure led advisors to avoid COIs, and then disclosed their freedom from conflicts to advisees. 

“Disclosure does not seem to be much good when conflicts are unavoidable, but it does seem to help when advisors have a choice about whether to subject themselves to conflicts,” observed Lowenstein. “A nice feature of disclosure is that it is, in effect, ‘self-calibrating’.  Doctors, for example, are unlikely to find it worth it to accept small gifts such as pens or calendars if the gifts are going to be disclosed.  Although larger gifts would be more tempting, doctors are likely to be deterred from accepting them because disclosure of large gifts would be more damaging to their reputations.”
