Investigation reveals 'optimistic bias' in impact investment practices
In a recent study published in the Journal of Business Ethics, researchers Lauren Kaufmann from the University of Virginia and Helet Botha from the University of Michigan-Dearborn have highlighted a concerning trend in the impact investing industry. According to their research, many investors are making decisions based on narratives or assumptions rather than on sustained, rigorous evaluation.
Kaufmann and Botha's study, titled "Who Loses in Win-Win Investing? A Mixed Methods Study of Impact Risk", is based on 124 interviews with impact investors from around the world and an online experiment with 435 participants. The researchers found that a common issue with impact investing decisions is what they call "wishful thinking." This occurs when investors rely on compelling narratives or assumptions about social and environmental outcomes, rather than on sustained, meticulous evidence and risk scrutiny.
One investor, who works in developing markets and has a background in water management, suggests that the impact sector could learn a thing or two from the history of economic development and the importance of fact-checking one's own assumptions, especially when investing in emerging markets.
The study also links this outcome to 'win-win' thinking, or the assumption that profit and social impact naturally go hand in hand, among investors. However, the researchers warn that this assumption can lead to unintended negative outcomes, such as a clean energy project displacing vulnerable communities or a healthcare initiative bypassing local needs, if impact risk isn't properly managed.
The researchers urge the impact investing industry to adopt better accountability measures. They suggest that investors should treat impact with the same level of scrutiny as financial performance, including tracking outcomes over time, engaging with affected communities, and more transparency about successes and failures.
Interestingly, the study reveals that few investors are truly concerned about impact risk once a company passes exclusionary checklists or ESG screening tools. A large minority of interviewees said they don't consider any kinds of impact-related risk at any point during the investment cycle.
The implications of these findings are significant, especially considering that $84trn is expected to be transferred from the baby boomer generation to younger investors by 2045. With impact investing having grown into a $1.5 trillion industry, according to 2024 statistics by the Global Impact Investing Network (GIIN), it is crucial that the industry adopts better practices to ensure that investments are delivering real impact as intended.
In the GIIN's two most recent surveys, only between 1% and 2% of investors reported falling short of their impact goals. However, the researchers argue that these figures may be unrealistically low given the complexities of development, health, education, and climate work. They emphasize the need to understand what works, what doesn't, and why in the impact investing field.
In conclusion, Kaufmann and Botha's study serves as a call to action for the impact investing industry to move beyond 'win-win' thinking and storytelling, and to adopt a more rigorous, evidence-based approach to decision-making. By doing so, they believe that the industry can ensure that investments deliver real, tangible results for the communities and ecosystems they aim to support.
Financial inclusion can be enhanced by adopting a more rigorous, evidence-based approach to impact investing, as suggested by the study conducted by Kaufmann and Botha. This approach could help investors avoid unintended negative outcomes and ensure that their investments deliver real social impact. To this end, development finance institutions might consider blended finance models that prioritize social impact and offer incentives for rigorous evaluation. Such models could attract more investors to the impact investing industry, fostering growth and contributing to social development.
