Even then, a large proportion of radiocarbon dating tests return inconsistent, or even incoherent, results, even for tests done on the same sample.The explanation given for these outliers is usually “contamination.” Inconsistent results are another reason why multiple samples, multiples tests, and various parallel methods are used to date objects.Carbon dating is reliable within certain parameters but certainly not infallible.When testing an object using radiocarbon dating, several factors have to be considered: First, carbon dating only works on matter that was once alive, and it only determines the approximate date of death for that sample.The other major factor affecting the results of carbon dating is gauging the original proportion of carbon-14 itself.Carbon dating is based on the loss of carbon-14, so, even if the present amount in a specimen can be detected accurately, we must still know how much carbon-14 the organism started with.Second, radiocarbon dating becomes more difficult, and less accurate, as the sample gets older.The bodies of living things generally have concentrations of the isotope carbon-14, also known as radiocarbon, identical to concentrations in the atmosphere.

That’s not unusual in science, so far as it goes, but the relationship between assumptions and interpretations must be kept in mind. At worst, it can make carbon dating circular and self-confirming, though there are other means of dating that can reduce this risk.Tiny variations within a particular sample become significant enough to skew results to the point of absurdity.Carbon dating therefore relies on enrichment and enhancement techniques to make smaller quantities easier to detect, but such enhancement can also skew the test results. As a result, carbon dating is only plausible for objects less than about 40,000 years old.Question: "Is carbon dating a reliable method for determining the age of things?" Answer: Carbon dating, or radiocarbon dating, like any other laboratory testing technique, can be extremely reliable, so long as all of the variables involved are controlled and understood.

As samples get older, errors are magnified, and assumptions can render carbon dating all but useless.
