While the phenomenological similarity described above is suggestive, more convincing evidence of an association between some dimensions of OCD and behaviours that minimize the risk of infection can be obtained from evolutionary theory. From an evolutionary perspective, disgust serves as a motivator in the avoidance of infectious disease, and has been linked most closely to the contamination/cleaning dimension of OCD. In conclusion, the above evidence suggests that there may be close links between some dimensions of OCD and behaviours that evolved to protect our ancestors from infectious disease, and which continue to do so now in a modified form.
