Bono’s TEDTalk aims to inspire its audience to address extreme global poverty and explain the history of anti-poverty campaigning. He motivates his audience, who are primarily people interested in addressing poverty but skeptical of the impact that is being made, largely be presenting data. His TEDTalk includes graphs that highlight the impact that previous interventions have had on poverty, AIDS, malaria, and child mortality.
One way in which he makes his presentation of data particularly effective is that he manipulates it to show statistics over short- and long time-scales. For example, when discussing child mortality rates, Bono presents the statistics on number of lives saved on a daily basis, making the impact seem much larger and much more tangible. However, when discussing the progress that can be made in reducing extreme global poverty, he shows data over large time-scales and includes projections, making it seem realistic that extreme global poverty could be ended by 2030.
The goal of showing this data seems to be to revitalize efforts to eliminate extreme global poverty. In particular, Bono aims to show that elimination of extreme global poverty is a realistic possibility within our lifetimes. In general, the way he presented his data seemed very effective. The data presentation made it clear that significant progress had already been made, and that based on what has already been done, elimination of extreme global poverty, which at first seems unrealistic, may be possible. However, the presentation could also be more effective because the examples he gives in the medical field show the amount of people whose quality of life has improved, but does not give a sense of to what extent the problem as a whole has been addressed.
