Optimal provision of information about consumption choices in the presence of a cognitive constraint

•A consumer can learn about her valuations for fewer goods than can be consumed.•The consumer should learn either about her worst and/or best choices.•More information about the worst choices is optimal when more goods can be consumed.

This paper studies how to best inform a consumer about her valuations for multiple goods when the consumer can learn about fewer goods than she can consume. The consumer should learn about the worst and/or best consumption choices. If the number of different goods that the consumer can consume increases, the consumer should learn about a greater number of goods to avoid and fewer goods to select.
