The Ambiguity Box: A new tool to generate ambiguity in the lab

• The Ambiguity Box is a software tool that visualizes uncertainty in laboratory experiments. • It is a virtual dynamic frame composed of squares that randomly change colours. • The tool overcomes the limitations of traditional devices like the Bingo blower. • It is adaptable to various experimental designs. • It is easily scalable to deal with low probabilities. The Ambiguity Box is a software tool that visualizes uncertainty in laboratory experiments. It is a dynamic frame composed of squares that randomly change colours, creating an uncertain and ambiguous environment. This encourages participants to infer the probabilities of each colour. The tool contributes to the economic literature by introducing a new layer of uncertainty, overcoming limitations of traditional tools like the Bingo Blower. The Ambiguity Box is more practical as it is software-based and can be used with any electronic device. It is flexible, allowing experimenters to predetermine the number of squares of each colour, making it adaptable to various experimental designs. It is easily scalable, suitable for use in different contexts, and allows for the exploration of decision-making under ambiguity in diverse settings, dealing also with extremely low probabilities.
