"But we now know that most people – around 71% - can voluntarily contract the inner portion of the orbicularis oculi."
I can't find the source for this anywhere online. My experience with over 100 hours of practice in front of a mirror (don't ask) and the research I've read suggests otherwise. And even if you can voluntarily contract your orbicularis oculi, you'll need to have the proper onset/offset times and constant intensities for muscle contraction, which are just as hard to fake and easy for a trained observer to spot.
I suggest the "crow's feet" from a Duchenne Smile is still a reliable indicator of feeling happy for all those reasons, if observed appropriately. It was far easier to fake a real smile by thinking of something happy, which is why facial recognition is still much better for emotion detection than lie detection.

- bryondowd 9y agoWouldn't your experience be at least as likely to mean that you are simply in the 29% of people who cannot do this? I would imagine people who can't flare their nostrils, roll their tongue, move their scalp (maybe this one is just me), or any number of other common but not universal movements would feel the same way you do at being told that these movements are not only possible, but quite common. I'm no trained observer, but looking at myself in a mirror right now, I can fake a smile that appears to me no different from a genuine smile formed while focusing on a happy thought. But I don't think I have a very expressive face in general, in addition to now knowing any key things to look for other than crows feet.
- arafa 9y agoEven if I am in the 29% (which is less likely, statistically speaking) along with my friend who also did the training and couldn't do this voluntarily, that's only one part of my argument. I'd still like to see the source for that data. It would contradict research that I've read. And voluntary movement still won't address onset, offset, and intensity of muscle contractions. In addition, voluntary facial movements will often be unilateral (one-sided) or asymmetric in some facet (stronger on one side than another) as well, among other concerns.
