I recently pointed out that although the Hawthorne Effect was real - the research that it was based on was flawed - yet we still call it the Hawthorne Effect. So in some ways it is a bit of a myth.
And then there was the Mehrabian Myth that 55% of the message is conveyed by our body language, 38% is conveyed by the tone of our voice and only 7% is conveyed by our actual words.
But I have now tripped over yet another widespread myth that 70% of organizational change initiatives fail.
I am as guilty as the next in "falling" for all three of these myths in past. It makes me wonder how many more common management concepts and practices we take for granted. Jack Martin Leith lists some more on his Debunking Unit website.
A resolution to myself "Question everything!"
