...For these reasons C14 dating is potentially unreliable. This is well known and documented. ..”

all radio-dating is fallible and prone to contamination (ALL). that is why it is unreliable.
It is a Fact, no two samples will give the result...unless , yes you test them 100 times and PICK the results.
It is dishonest!!!

and that is how it is done.

and the article illustrates the bias when testing samples.

The current method of Earth-age calculation is done by measuring isotope ratios is Uranium samples. It is possible that any given sample may be contaminated with exactly the amounts of the various daughter elements needed to present a false reading.

It is insanity to belive that they are all contaminated with exactly the right amount of all of those elements.

That the article and it's presentation illustrates bias is not in question. Who's bias is being illustated apparently is.
