The first thing I notice is that both the first and last authors of this paper are industry-affiliated. Not to say there's anything inherently problematic with that, but at least raises an eyebrow about the motivation behind this study.
I wonder how this study can be used as evidence against determinism, ie., that humans really do possess free will. If the coin toss relevantly affects the person's decision, then it seems like random chance plays a key role in affecting our experience, right?
Hate to rain on this person's parade, but his findings are mostly meaningless. You cannot simply infer neurological activity from a single electrode. Besides the need for a proper ground/reference, you also need electrodes placed in the correct anatomical locations to derive any meaningful insights into attention networks.
I imagine that after 30 minutes of being inclined while using the keyboard/mouse, the reduced blood circulation in your hands and arms from gravitational resistance will cause them to be incredibly tired/ fatigued.
At the end, I couldn't help but try to derive some overall take-away. The best I could come up with was to cherish your friendships and always try to keep in touch. One concern I would have is whether or not today's internet-based culture could hinder this?
The view of brain oscillations driving (or even partially modulating) neural activity is further supported by research involving stimulating the brain using Alternating Currents [1] I'm currently doing my PhD on this topic, and it seems so far that targeting AC (with an entrained frequency) to various motor-related neural networks can actually enhance the motor skill and even motor learning.
Brain oscillations are quite phenomenal, and the causal role of these synchronisations still require further research.
The only way this would be a killer feature in my book is if it analyses my entire inbox to generate the result. It would be more realistic since it is actually based on email and not published writing samples, which are not always indicative of communication.
I would venture the trend is because there are consumers (maybe a significant percentage) who, when comparing different options, simply make a choice based on "bigger is better".
