Light can travel 3000 miles (across the country) in about 16 milliseconds (source: the Google) so unless you're complaining about latencies in that range, i don't think the speed of light is your problem. The packets being caught and retransmitted by many devices along the way is much more responsible for the latency.
Yeah, the headline couldn't be more wrong. These subjects had no incentive or reason to lie or to tell the truth - they had a free and unbiased choice between lying and truth-telling, and the magnets affected their arbitrary decision. It's not like they wanted to lie and couldn't.
