This paper examines the possibilities of using the crowdsourcing strategy for theory testing. We first analyse the relationships between theory building and theory testing activities. Then, based on a systematic review of 248 papers published in MISQ, we characterise the intents and pat-tern systems of activities that have been used for theory testing. Finally, we ascertain which ac-tivities can be crowdsourced or not and pinpoint a set of pathways supporting partial and total crowdsourcing. The obtained results show that a large number of activities related to data gath-ering can be crowdsourced, and that a number of intents have viable pathways supporting par-tial crowdsourcing.
