The article doesn't explain what 'spatial intelligence' actually is. There's a link to a paper that goes on and on about 'spatial ability', but never defines it. As if 'IQ' wasn't useless enough, they had to come up with with 'EQ' and now everyone and their brother tacks 'intelligence' after a phrase they think should be desirable. Not to mention the fact that every test I've ever taken did include a section testing this 'spatial ability' (the paper contains examples, so I can infer what it means).
