The dirty work of ACH is much easier with the PARC software. It handles both inconsistency and weighted inconsistency scores. You can sort evidence by order addedd, diagnosticity, type, credibility, relevence, or even user criterion. Best of all it comes with a built in ACH tutorial that will guide you through the process if you are a newbie or just a little rusty.
If you hooked your laptop to a large screen monitor or multimedia projector PARC ACH would make a good collaborative tool. The whole team could readily see the effects of changes without being slowed by the need for someone with neat handwriting.
Did I mention that it is free?
The chart above was generated when I compared relative interest in Darfur, Iraq, Afghanistan, and the Congo, with Sweden as a control.
The results were pretty interesting. Searches for Iraq seem to correspond with increases in media coverage. No surprises there. The big surprise for me was Sweden. Google user are more interested in Sweden than they are in Darfur, Afghanistan, and the Congo. Talk about forgotten conflicts!
Flag B is interesting. It marks George Bush's call for more NATO troops in Afghanistan and clearly shows an increase in media coverage of Afghanistan. It even overtook coverage of Iraq for a short while. However, the general public took no notice.
The regions chart is enlightening. Americans are predominantly interested in Iraq and seem to have forgotten about Afghanistan. The Canadians, who have troops in Afghanistan but not Iraq seem equally interested in both countries. And finally, the Swedes seem to be totally obsessed with Sweden.
Not without trepidation replaced Sweden with "beer" in my search terms. I shouldn't have. I now know that your average computer using westerner is more interested in beer than they are in Iraq and Afghanistan combined. "Darfur?... never heard of it... do they have good beer?"
If you are feeling particularly masochistic try breakfast or worse boobs. For a brief while in 2004 your average Google user was more interested in what was happening in Iraq than what they were going to have for breakfast. That aberration hasn't repeated itself since. Its also interesting to note that while American's seem equally fascinated by Iraq and breasts, Canadians have a distinct preference for the later.
