`  == 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[15] that are not based on solid science.[16]`` :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.    `
