Carbon-14 dating is the center of debate as it pertains to dating from the Iron Age period. This off-site article illustrates the general propensity of scholars to reject the more substantial and reliable methods of pottery dating and other historical synchronisms involving ancient records and eyewitness testimony. Here is an excerpt:
The date of the transition from the archaeological period known as Iron Age I to Iron Age IIa is a particularly hotly disputed topic, especially because the date of the transition is crucial for elucidating the history and material culture of the reigns of David and Solomon. According to the so-called high chronology, the transition occurred around 1000 or 980 B.C.E. It is generally recognized that David conquered Jerusalem in about 1000 B.C.E. According to the low chronology, the transition to Iron Age IIa occurred around 920-900 B.C.E. Other opinions place the transition somewhere between the two-in about 950 B.C.
Often, laypersons are not aware the C-14 testing involves ratios of C-14 and C-12, NOT DATES! The dates must be calibrated and are based on unprovable assumptions about the past. The same problem is found in dating Jericho and other sites in the ANE in the Second Millenium B.C. Dr. Wood has commented here briefly on this important subject: Carbon 14 Dating at Jericho
