How often is c14 carbon dating inaccurate?

Question

Please cite sources if possible.

Answer 1

Pretty much most of the time. Look at what is supposedly said was dated accurately, but test again, and you have your errors. I'd say about 80% of the time.

Answer 2

The accuracy of radiocoarbon dating was tested on objects with dates that were already known through historical records such as parts of the dead sea scrolls and some wood from an Egyptian tomb. Based on the results of the Carbon 14 test the analysis showed that C14 agreed very closely with the historical information.

Copy and Paste:

It is important to note the meaning of "accuracy" and "precision" in radiocarbon dating. Accuracy refers to the date being a 'true' estimate of the age of a sample within the range of the statistical limits or ± value of the date. Thus, for the sake of argument, if we were radiocarbon dating a sample of Harold 1's (d. 1066) remains, and obtained a date of 1040±40 AD, we would have dated the event of his death accurately. If however the date were 1000±15 AD, we would be inaccurate. In terms of precision, however, the former is imprecise in comparison to the latter. It can be seen that the date of 1000±15 AD while being highly precise is, in this instance, inaccurate.

Answer 3

If the lab work is done well, the dates are very accurate. If the lab uses sloppy procedures the results will suffer.
