Point on a scale

@Bombastic and all

We are, basically, primates running modified software and as such I suspect that we are adapted to monitor our surroundings for things that *change* from the norm. Hence the increased usability of big fat gauges and levers, as Mr Bob says, you develop awareness of what looks like a normal pattern and can detect and deal with any departures.

Teaching basic maths to teenagers has paid my rent for several decades. When you say a number like 14.6 I immediately see a pointer on some kind of scale (because I'm old) and I'm thinking 'could be anywhere between 14.55 and 14.65, 20 is close, 10 is closer and it is nowhere near 146'. The younguns are just seeing digits - numbers in a line - no obvious awareness of what other numbers are near or far (14.7 as opposed to 146).

How we get round this I'm not sure.
