I question the dataset used for this and the basis. They used "self-reported political orientation, age, and gender" and "facial images (one per person) were obtained from their profiles on Facebook or a popular dating website". I first question the ethics of what sounds like a Facebook scrape. Second, I wonder how well they normalized across the terrible filters and frames and variations in pose. Finally, I question the basis in regards to the ability to gauge one's "openness to experience" let alone, say, "opinion on immigration policy" from micro-expressions in the face (or at least those which could be interpreted by a VGG based facial recognition algorithm). Edit: One last rant about this palm-reading-esque pseudoscience: I hate that this was put out in the universe, and thus potentially giving the wrong person ideas.
