Are carbon dating and other dating methods empirically accurate?

Radiocarbon dating is accurate enough on long expired life.

It uses the unstable 14C isotope, which has a half life of 5730 years.

I once read about rocks that were dated to 3.2 billion years by five different methods with perfect agreement, allowing for the small uncertainties in each.

Although carbon 14 dating is very useful as the proportion of C14 is derived from cosmic ray radiation it gives the best results when it can be calibrated against historical or tree ring data.

It seems almost entirely random whether she and I get on or not ;-)
