Understanding RADCAB - Currency in Issues in Technology

What it does: Currency is the C in RADCAB and comes fourth. This is exactly what the Currency check looks for. Currency checks when information was written or updated. Checking who wrote it is Authority, not Currency. Technology changes fast, so a 10-year-old article is likely outdated. Price isn't checked by Currency at all. Checking evidence is Detail, not Currency. Currency is the check for how recent a source is.

Common mistakes: Price isn't checked by Currency - it checks how recent info is. Checking the author is Authority, not Currency.
