Empirically, there's small to no scientific evidence promoting the metaphysical statements created by ACIM. The idea that the bodily earth is an impression created by our collective ego lacks scientific support and works counter to the vast body of scientific knowledge accumulated through generations of statement and experimentation. While subjective activities of transcendence and spiritual awareness are well-documented, they do not provide goal evidence of the non-dualistic reality that ACIM describes. Additionally, the course's assertion that adjusting one's feelings can alter fact in a literal sense is reminiscent of the New Thought motion and the more recent law of attraction, equally of which have been criticized for lacking medical validity. The placebo influence and the power of positive thinking are well-documented phenomena, but they don't help the great metaphysical states made by ACIM.

Furthermore, the beginnings of ACIM raise additional questions about its credibility. Helen Schucman, the psychologist who transcribed the program, defined her experience as receiving dictation from an inner voice she recognized as Jesus. This method of channeled writing isn't special to ACIM and are available in many other religious and religious texts all through history. david hoffmeister  The subjective nature of these experiences causes it to be difficult to confirm their authenticity. Critics fight that such texts are more likely products of the unconscious mind as opposed to communications from the divine source. Schucman himself had a complex connection with the product, allegedly experiencing significant inner struggle about its content and its beginnings, which provides another layer of ambiguity to the course's claims of divine authorship.

In addition, the language and design of ACIM in many cases are clever and abstract, which makes it hard for many visitors to comprehend and use its teachings. The class is prepared in a very stylized form of British, with thick, lyrical prose that can be tough to interpret. That complexity can result in a wide variety of understandings, a number of that might diverge somewhat from the intended message. The ambiguity of the text makes for subjective numbers, which may result in misconceptions and misapplications of its principles. This lack of quality can undermine the course's success as a practical manual for spiritual growth and self-improvement.

More over, the commercial part of ACIM can't be overlooked. Since their publication, ACIM has spawned a profitable market of publications, workshops, seminars, and examine groups. While economic success does not inherently eliminate the worth of a religious teaching, it will increase problems concerning the prospect of exploitation. The commercialization of spiritual teachings can occasionally result in the prioritization of income over true spiritual progress, with persons and businesses capitalizing on the course's popularity to promote products and services. That energetic may deter from the sincerity and reliability of the teachings, throwing doubt on the motives behind their dissemination.
