The questions were about which properties the Singularity Institute would need to possess in order to successfully recruit young mathletes. The two most common answers were "previous technical results" and "one or two cool people already on the team." (But, for example, most people didn't care about peer review.) It seems that mathletes wanted to be able to see that these problems were tractable not just to humans but also to the Singularity Institute in particular. That sounds reasonable, of course, but self-reported motivations are often wrong, so we're in the process of gathering additional forms of data, too.
