Ambiguity aversion is the cognitive bias where people prefer known risks over unknown risks, even when the unknown option could yield better outcomes. In crypto, it manifests as:
A salaried woman in Pune was offered two investment choices by her bank. The first was a fixed deposit offering 6.5 percent interest with fully known terms. The second was a new market-linked structured product that claimed the possibility of higher returns but did not clearly explain how those returns would be calculated or what risks were involved. Even though she had a long-term horizon and enough savings to absorb short-term fluctuations, she chose the fixed deposit. Her decision was driven by the discomfort of not knowing how the structured product worked, how often returns might vary, or what conditions triggered losses. The absence of clear information made her avoid the uncertain option, even though it had a reasonable chance of performing better.
Ambiguity aversion was formalized by Daniel Ellsberg in the 1961 Ellsberg Paradox. In finance, it explains why investors favor known risks (blue-chip stocks) over high-potential but unfamiliar opportunities—mirrored today in crypto investing behavior.
