"Uncertainty is the only certainty there is, and knowing how to live with insecurity is the only security." – John Allen Paulos
Imagine you are presented with two investment options. The first promises a guaranteed return of 5% over the next year, while the second offers an unpredictable return, possibly as high as 10% or as low as 0%. Which would you choose? Most people tend to opt for the certainty of a guaranteed return, even if it means potentially missing out on a higher yield. This inclination to favour known outcomes over ambiguous ones reflects a cognitive bias known as the Ambiguity Effect. In the world of investments, this bias can significantly impact decision-making processes, potentially leading to missed opportunities and suboptimal portfolio management.
Understanding the Cognitive Biases
Cognitive biases are inherent mental shortcuts that influence how we perceive and process information. They can often lead us to make decisions that deviate from rationality and logic. Ambiguity Effect, in particular, stems from a deep-seated aversion to uncertain or ambiguous situations. Individuals tend to prefer known risks over unfamiliar or ambiguous ones, even if the latter may offer a potentially more favourable outcome. Some of the other cognitive biases that we have talked about in our Behavioural Finance series include Base Rate Fallacy and Anchoring Bias.
A Fascinating Demonstration
What do the three displays in this figure share in common? They all possess an element of ambiguity. While it's highly probable that you perceived the left display as A B C and the right one as 12 13 14, the figures in the centre in both presentations are identical. There was also the potential to interpret them as A 13 C or 12 B 14, yet this possibility was not considered.
The reason for this neglect lies in the influence of the context, wherein the shape is perceived as a letter within the framework of letters and as a number within the context of numbers. The overall context significantly influences the interpretation of each element.
Despite the ambiguity inherent in the shape, a prompt conclusion is reached about its identity, leading to the oversight of the underlying ambiguity that was resolved. Similarly in the text given in the middle, the mention of "Ann" likely conjured an image of a woman preoccupied with financial matters in your head.
However, this interpretation is not the sole interpretation possible. The sentence itself is ambiguous. Had the preceding sentence been "They were near the river” a completely different mental image would have been evoked. When the mind is focused on a river, the word "bank" does not necessarily evoke associations with financial institutions.
In the absence of explicit context, our intuition tends to construct a probable context on its own, guided by recent experiences. Notably, we often remain unaware of the decision-making process or the possibility of alternative interpretations.
Recent events and the immediate context hold more weight in determining an interpretation, whereas more distant memories come into play when no recent event readily comes to mind. Deep-rooted childhood experiences, like learning the alphabet, shape our cognitive processes, leading to an interpretation of "ABC" rather than "A13C." The crux of both examples lies in the fact that a definitive choice is made, yet our awareness of this decision remains elusive. Only one interpretation emerges while the underlying ambiguity remains hidden from conscious vision.
How Does it Play in Our Daily Lives?
The effects of the Ambiguity Effect extend beyond the realm of finance, permeating various aspects of our daily lives. Consider the reluctance to try a new restaurant because the menu descriptions are unclear or the hesitation to pursue an unfamiliar career path due to a lack of certainty about its prospects. These instances illustrate how our aversion to ambiguity can impede our willingness to explore new opportunities and experiences. This translates to risk aversion in the face of unavailable data, or ambiguity. We might miss out on great options just because we have definite data about one option and no information about the other. While it might be the case that the option with no information might be the best one to pick!
Effect on Investment Decisions
In the context of investments, the Ambiguity Effect often translates into investors opting for safer, low-risk assets over potentially higher-yielding but less predictable ones. This tendency can limit the diversification of investment portfolios, leading to missed opportunities for significant returns. Moreover, investors may overlook emerging markets or industries with uncertain prospects, despite their potential for substantial growth. As Warren Buffett famously advised, "Risk comes from not knowing what you're doing.”
In the world of value investing, the art of picking stocks with lower intrinsic value happens in a paradigm where the information is scarce. These stocks remain low profile and under the radar of most investors because there are not enough headlines about them. While on the other hand, there might be information overload about other companies, and industries which might create a bias for certainty, nudging the investors away from great prospects that lie just under the surface, if only they would look closer.
Ambiguity Effect on Financial Advisory
Financial advisors often encounter the Ambiguity Effect among their clients, as investors tend to seek guidance that aligns with their desire for certainty. Advisors must navigate this bias by effectively communicating the potential benefits and risks associated with different investment options. Failing to address the Ambiguity Effect can lead to misaligned investment strategies, hindering clients from maximising their portfolio's potential.
Solutions
To mitigate the adverse effects of the Ambiguity Effect, investors and financial advisors can employ various strategies. Conducting comprehensive research, performing thorough due diligence, and diversifying investment portfolios can help mitigate the aversion to uncertain outcomes. Additionally, fostering a mindset that embraces calculated risk-taking and strategic decision-making can enable investors to capitalise on opportunities that may otherwise be overlooked.
How to Tackle the Ambiguity Effect?
Preventing the Ambiguity Effect requires a proactive approach to decision-making. This involves consciously acknowledging the bias and actively challenging it by seeking diverse perspectives, engaging in open discussions, and fostering a willingness to explore and understand unfamiliar opportunities. Employing analytical digital tools and models that incorporate a range of potential outcomes can also aid in making informed investment decisions that consider both known and ambiguous risks.
The Gist
The Ambiguity Effect, a cognitive bias favouring known outcomes over ambiguous ones, significantly impacts investors' decision-making. The Ambiguity Effect can lead to a preference for low-risk assets, limiting portfolio diversification and potentially overlooking high-growth opportunities. Financial advisors must navigate this bias, emphasising the need for comprehensive research and a mindset that embraces calculated risk-taking. To prevent the Ambiguity Effect, proactive strategies include acknowledging the bias, seeking diverse perspectives, and utilising analytical tools to make informed investment decisions. In a world where uncertainty is an inevitable part of the investment landscape, recognising and addressing the Ambiguity Effect is crucial for investors and financial advisors alike
