Neuromarketing - not ready for prime time...

I don't usually react to emails suggesting that mindblog consider mentioning what turn out to be commercial sites, but I thought the points raised by Dan Hill in this article (PDF) were quite interesting, apart from the fact this his company, Sensory Logic, would like to sell your business their services on facial analysis of emotional reactions to stimuli or services. His contention is that facial coding, which follows the response of 43 facial muscles that signal emotion, is superior to other emotional monitors such as EMG (bio feedback), EEG (electrical activity on or just below the scalp), or fMRI (brain scans).
