Data insights are again the key to funnel optimization. Three other data-driven technologies follow analytics and sales reporting as the most popular sales tools: account and contact management (65%), sales forecasting tools (56%), and customer relationship management (CRM) systems (58%).

In brief, we are inclined to go along with someone’s suggestion if we think that person is a credible expert (authority), if we regard him or her as a trusted friend (liking), if we feel we owe them one (reciprocity), or if doing so will be consistent with our beliefs or prior commitments (consistency). We are also inclined to make choices that we think are popular (consensus [social proof]), and that will net us a scarce commodity (scarcity).
