Good question. It seems that academic philosophy does, to an extent, achieve this.

With some of my engagements with academic philosophers in mind I have at times been tempted to lament that that 'extent' wasn't rather a lot greater. Of course, that may be 'the glass is half empty' thinking. I intuit that there is potential for a larger body of contributers to have even more of a correcting influence of the kind that you mention than what we see in practice!
