Andrea and Casey are grappling with what it is to be intelligent this time on ThunkTink - sticking to those easy, non-contentious topics. Ideas bounced around our collective brains include: Can we test if animals can discriminate between twins? How do we best "share" intelligence? How do we best "support" its development - what does the even mean? Are more intelligent species more adaptive to new environments? Can we come up with a better way to display and communicate someone's intelligence (rather than grades/IQ scores)???
