Edit request  repetitive sentence and poor reference   For most of its existence it has battled with mainstream medicine sustained by pseudoscientific ideas such as subluxation and innate intelligence that are not based on solid science The end of this sentence is repetitive information as not based on solid science just echoes the meaning of pseudoscientific ideas and should be removed The attached reference is very poor quality and should be removed with the phrase mentioned above It contains one link to a WP article and two more links to tertiary or even worse review articles bordering on blog level References have already been supplied after innate intelligence and more poor quality references just make clutter and look over biased making a point
