CREDIBILITY OF OPINION WITNESSES
Testimony has been introduced of certain witnesses who purport to be skilled in their line of endeavor or who possess peculiar knowledge acquired by study, observation, and practice.
You may consider the testimony of these witnesses, and give it such weight and value as you think it should have, but the weight and value to be given their testimony is for you to determine. You are not required to surrender your own judgment to that of any person testifying, based on that person's education, training or experience. You need not give controlling effect to the opinion of such witnesses for their testimony, like that of any other witness, is to be received by you and given such weight and value as you deem it is entitled to receive.
