In this chapter, I consider whether there is a case for favoring interventions whose effectiveness has stronger evidential support, when expected effectiveness is equal. I argue that in fact the reverse is true: when expected value is equal one should prefer to invest in interventions that have less evidential support, on the grounds that by doing so one can acquire evidence of their effectiveness (or ineffectiveness) that may then be valuable for future investment decisions.
