An anonymous reader writes with news that the NSF has just awarded a group of researchers a grant to study the life cycle of memes. "Indiana University is receiving nearly $1 million in federal grant money to investigate the genesis, spread, and demise of Internet memes. The grant from the National Science Foundation awards four Indiana researchers $919,917 to for a project called Truthy that will, as the grant's abstract explains, "explore why some ideas cause viral explosions while others are quickly forgotten." (And yes, in case you're wondering, the name was inspired by Stephen Colbert's neologism "truthiness.") The government-funded research is aimed at identifying which memes are organic and which ones are mere astroturf. "While the vast majority of memes arise in a perfectly organic manner, driven by the complex mechanisms of life on the Web, some are engineered by the shady machinery of high-profile congressional campaigns," Truthy's About page explains."
