Before I strap electrodes to my skull, I am going to need more convincing than "An article online said...". I am surprised at how many smart people are willing to try this despite the lack of evidence / research.

If I wanted to increase my productivity, I would start by not surfing hackernews. Eventually, I might move on to "home made electric chair I bought off ebay", but I think I will exhaust other possibilities first.

But, hey, that's me. :-)
