Saving energy
Number one complaint among listeners today was my attempt to stop Hilary Benn reading out the phone number of the Advice Centre on the radio.
I said it was a waste of our time - and promised we'd put the number on the web.
Well, I didn't mean to imply that everybody has access to the web. Nor to imply that the Energy Efficiency Advice Centre telephone number is unimportant. In fact, I think it is rather good for us to provide news you can use - and sometimes that will involve handing out a phone number.
But be realistic: I suspect more people have the internet - by some margin - than have the skill of memorising a six digit number (excluding the 0800) read out once with a nano-second of advance warning.
Reading the telephone number out in the interview probably achieves only three things: it sets some people scurrying in frustration to grab a pen which they find too late to write the number down; it tells people there is a phone number they can find later...and above all, it diminishes the valuable and limited time the minister has to answer the question he is confronted with on the significance and likely efficacy of his policy.
But this is a bigger issue for radio than telephone numbers. The medium is uniquely ill-suited to any numbers, such as financial data. For large volumes of digits (which you can for example see on Bloomberg television and in the FT) the consumer needs to be able to select a particular fact or two that they need. And to be able to "re-wind" - to get more than one viewing of the data.
That is just the way I think most of our minds work.
The fact that radio is so hopeless at delivering data makes it an uncluttered medium offering the basic story without the detailed trappings. But it does mean that if data is important, radio is probably not your place.
But not all is lost: radio can do numbers. It just needs to offer them sparingly, it needs to signpost them and if they are important it needs to repeat them.
If ministers can give us a little warning of their need to present their phone numbers, we can ensure the best standards of radio data presentation are adhered to.
