The Tipping Point, Malcolm Gladwell describes how ideas spread through society, following "epidemic-like" dynamics. At one point he includes a provocative passage about AIDS, and what would have happened had we not discovered the virus. I include it here as food for thought:
"Not long after The Tipping Point came out, I happened to talk to an epidemiologist, a man who had spent the better part of his professional life battling the AIDS epidemic. He was a thoughtful fellow, and frustrated in the way that someone would be who has had to deal, on a daily basis, with such a terrible disease. We were sitting in a cafe talking about my book, which he had read, and then he said something startling: "I wonder if we would have been better off if we had never discovered the AIDS virus at all?" I don't think he meant that literally, or that he regretted the countless lives that have been saved or prolonged by anti-HIV drugs and the AIDS test. What he meant was this: that the AIDS epidemic is fundamentally a social phenomenon. It spreads because of the beliefs and social structures and poverty and prejudices and personalities of a community, and sometimes getting caught up in the precise biological characteristics of a virus merely serves as a distraction; we might have halted the spread of AIDS far more effectively just by focusing on those beliefs and social structures and poverty and prejudices and personalities."
