I don't know if it's ever been tested...but if you were to take an election campaign ( like the 2 year presidential election ) and place the emphasis on one side winning, only showing poll results that favor that side winning, make special efforts in news stories that relate to that side winning...
would you in effect be responsible for that side winning?...eg. for the last 6 months or so it has been constantly reported that Obama was ahead in the polls, and I wonder how much that impacted on his being ahead in the polls...
do you think that ' speculative election reporting ' should be stopped...in other words should the media not report in such a way as it may manipulate or impact upon the results?
