False metrics are everywhere in our media. There’s a TV commercial from QBE insurance that asks,

“What's the chance of this young woman getting a great deal on car insurance? Maybe five per cent? Ten per cent? Actually it’s one-hundred per cent, because we know she’s a safe driver.”

After fielding yet another annoying marketing call Jess observed that we should have a government bill that says, as is the case with vampires, telemarketers can only come into our home if we invite them.

The larger and more complex the subject matter, the harder it is to develop meaningful learning experiences. Without a clear idea of the big picture there's a risk of concentrating too heavily on some learning points while skipping others entirely. It becomes easy to get lost in the information wilderness. More pertinent still is that when you're dealing with complicated or technical topics there's a very real risk of misinterpretation (or just plain getting it wrong), particularly if you as the designer are not well versed in the subject at hand.
