Reportedly, Ben Goertzel and OpenCog were intended to add credibility through association with an academic:

It has similarly been a general rule with the Singularity Institute that, whatever it is we're supposed to do to be more credible, when we actually do it, nothing much changes. "Do you do any sort of code development? I'm not interested in supporting an organization that doesn't develop code"—> OpenCog—> nothing changes. "Eliezer Yudkowsky lacks academic credentials"—> Professor Ben Goertzel installed as Director of Research—> nothing changes.
