Pursue high impact/high risk strategies, with appropriate contingencies.

If many links in a results chain have weak evi­dence, but the poten­tial ROI and impact are high, con­sid­er risk mit­i­ga­tion efforts, and deploy the strat­e­gy adap­tive­ly with focused mon­i­tor­ing to learn about effec­tive­ness. It is impor­tant to ensure, how­ev­er, that the strat­e­gy is not pos­ing a high risk of neg­a­tive impacts to vul­ner­a­ble people.
