According the the Association for Customer Research “Numerous studies have shown that the longer the time interval between  measures of intention and behavior, the greater the inconsistency in behavior. Empirical  evidence is presented to support the theory that this time effect on behavior  inconsistency is partially a function of unexpected situational variables. Unexpected  situational variables were also shown to affect changes in intentions over time”. (Joseph A. Cote Jr. and John K. Wong (1985). This appears to affect the outcome more than some of the other variables. Extraneous Variables In Research Survey Assignment Papers.
