Following on from the previous post concerning availability bias, there is another inherent bias we must be aware of. Its called framing bias.
How do you view situations? What is you standard perspective? To extend the analogy, through which window frame are you seeing the issue?
And so, to increase your understanding of a situation you need to be aware of your, and others, framing bias. To go one step further, why do you always use a particular frame?
The other side of the coin is the framing of the issue. What do you want people to see? What choices do you want the audience to make? Would you rather report on a change in terms of percentages or absolute figures? How do you want to frame that change? How do you want the audience to react?
