I made a reddit account to specifically respond to this. I am a neuroscientist, I work at one of the biggest universities for cognitive neuroscience in my country and have done work on multi-tasking and attention in the past. We run studies that cost $3000-$5000 per participant and never once have we published results we've gotten with only 12 participants. Even on the most expensive studies we've done, we generally have a minimum of 40 participants. I realise that not all labs have the same amount of money and ability to do this, but don't claim that 12 participants is a "perfectly valid sample size" when you're splashing your results all over the news.
