Two Heads Are Better Than One For Brain-Computer Interfaces 57
FatLittleMonkey writes "My mind to your mind... my thoughts to your thoughts... Researchers at the University of Essex have shown that combining the output from two non-invasive 'brain-computer interfaces,' computer-interpreted EEG signals, led to a much clearer signal of the subjects' intention than the output from a single subject. To test this idea, they had two subjects try to steer a simulated space-ship at a target planet, by thinking of one of eight possible directions. While a single user could achieve 67% accuracy, this jumped to 90% when two minds were combined. Researchers believe the technique also compensates for individual lapses in attention, and thus may have applications in real-world space missions."

with the addition of another brain it became "crowd intelligence" or "crowd sourced" and is now sufficiently buzzword compliant.

"It is difficult to stay focused on the task at all times. So when a single user has momentary attention lapses, it matters. But when there are two users, a lapse by one will not have much effect, so you stay on target,"
They correlate inputs from two pilots to improve accuracy, but at the same time in the quote above they assume that the inputs from the pilots would not correlate. Its is not like two pilots in a jet liner would miss something as big as their destination airport. [go.com]

Yes, it is true, I lived in Hamburg that time. They had big trouble to get the bird into the air again as the runway was way too short.

Anything they do does require they can calibrate on a single individual. Just taking measurements from two individuals (with each their own calibration) will always be better. That has nothing to do with neurology, that is just signal processing 010.

God's way is what? Capitalism? I don't think so. If God subscribed to any ism's, communism would be as likely as any. At it's core, before the addition of greed and corruption, communism intends to take care of everyone, and to eliminate the rich, the poor, leaving only a middle class. "Give what you're capable of giving, and take what you need" almost sounds biblical. Almost.

Actually, a ton of Christian philosophers, economists etc. have tried to answer that. The best result of their attempts, as far as I know at least, is that of what we'd call a "3rd way", called "Distributism".
Distributists agree with communists in the centrality of the means of production, and that it shouldn't be in the hands of a few for them to use it to exploit the masses. Contrary to communists, however, they also don't think it should be in the hands of a single one (the state), but rather spread amon

Yep. I like to make a distinction between "Catholicism the religion" and "Catholicism the philosophy". They overlap quite a bit but one can be taken without the other and the later is much more interesting and universally applicable than the former. I myself am not Catholic, but I do absorb quite a bit of their philosophy. After centuries of very serious intellectual development it acquired a "solidity" that most alternatives lack. As such, it's a joy to study for those so inclined, even if they disagree wi
