When individuals experience information overload, it can impair their judgment by causing them to limit their information search and use simple heuristics instead. Given the well-documented use of heuristics in retirement plan investing, as well as the prevalence of biases such as the default bias and inertia, it is very possible that information overload is a contributing factor (see Agnew, forthcoming, for an overview).

We find that financial literacy plays an important...
