For reasons best known to them (probably), the BBC World service came up with a poll to measure selected countries’ perceptions of certain other countries’ influence.
Since the BBC and the BBC World Service have been pumping out selected information about the aforementioned countries, and withholding certain other selected information, it throws up an analogy thus:
I run a monopolistic campaign to promote my product for a number of years. I also run a monopolistic negative campaign to discredit my rivals’ products. I then send out a questionnaire to random consumers and non consumers asking whether they see my product in a positive or negative light.
Since most of the participants in question have been subjected to my campaign but many of them have never tried my somewhat niche product because it isn’t relevant to them, the results cannot show how popular my product is, merely how effective my campaign has been.
The BBC World Service can rest assured. Their campaign has been a great success.
