In research dealing with hindsight bias, there are still controversies regarding why hindsight bias occurs. This could be partly because the hindsight bias that a person experiences, might differ depending on what method has been used to assess it. In some situations, for example, if we use what has been called the hypothetical design, we find greater hindsight bias than if we use a memory design to assess hindsight bias. One way to understand to explain why one design shows more bias than the other in some situations is to use individual difference variables such as strength of handedness. Previous studies show that mixed (or inconsistent) handers show more anchoring than strong (or consistent) handers and that mixed handers have a better episodic memory as compared to strong handers. Interestingly, these differences related to the underlying processes of the two different hindsight bias designs. Our results show that for the hypothetical design, where participants do not have a previous response with which to compare, participants tend to anchor to the given feedback when feedback is available. In the memory design, where participants have to compare their present response with their past response, episodic memory plays a major role in such situations. In the present study we found that in hypothetical design mixed handers showed greater hindsight bias as compared to strong handers, whereas in memory design strong handers showed greater bias as compared to mixed handers. Thus our present study concludes that underlying mechanism of hindsight bias differs depending on what design has been used. Strength of handedness helps to understand the underlying mechanisms for occurrence of such differences and it could be a useful tool to predict in what situations the memory design would exhibit greater hindsight bias and in what situation the hypothetical design would show greater hindsight bias
