Can Radioisotope Dating Be Trusted? by John D. Morris, Ph.D. For
decades creation scientists have shown that the answer to this
question is a clear NO! Its results have been shown to be
inconsistent, discordant, unreliable, and frequently bizarre in
any model. Creationists have, in particular, pointed out the
weak assumptions on which the method is based, and the
contradictory nature of its results. A research consortium has
recently convened at ICR to go further and develop a workable
understanding of the radioisotope decay data from a young-earth
perspective. The old-earth model doesn't work, and a better
model must replace it. However, as we look forward to a better
alternative, it would behoove us to look back and restate the
powerful tried and true arguments relating to the erroneous
assumptions and contradictory results. Assumption One: The
radioisotope decay rates have been constant throughout the past.
We know that some elements decay over time into another element,
i.e., uranium (parent) changes into
