: A minimalist, critically acclaimed art-house film directed by Paheli (2005 Film)

In many real-world settings—ranging from microfinance contracts to public health guidelines—decision-makers face environments so confusing that they resemble riddles ( paheli ). This paper proposes a novel composite metric, the Index of Paheli (IoP), to quantify the degree to which a choice environment impedes rational decision-making through ambiguity, complexity, and contradictory cues. Drawing on behavioral economics, information theory, and psychometrics, the IoP integrates three sub-indices: (1) Structural Complexity (e.g., number of steps, conditional clauses), (2) Informational Asymmetry (gap in understanding between expert and layperson), and (3) Contradiction Density (frequency of internally inconsistent signals). We derive a mathematical formulation, test it on hypothetical financial products, and discuss policy applications in consumer protection, development interventions, and digital interface design. The IoP offers a practical tool for regulators and researchers to identify and reduce “puzzling” environments that disproportionately harm cognitively burdened populations. index of paheli
