Another stage of review is the possible lack of empirical help for the states created by ACIM. The course asserts that their teachings can result in profound spiritual transformation and healing, but these states are not supported by scientific study or clinical studies. Without scientific evidence to back up their assertions, ACIM depends heavily on historical evidence and particular recommendations, which are inherently subjective and unreliable. The lack of arduous, purpose study helps it be difficult to determine the true effectiveness of the class and improves issues about its overall legitimacy.

The commercial facets of ACIM also ask skepticism. Because their book, the program has spawned a multi-million buck market that includes david hoffmeister  books, workshops, seminars, and on line courses. Authorities argue that the commercialization of ACIM undermines their spiritual information and raises ethical issues concerning the motivations of those that promote it. The high expenses associated with participating in ACIM-related actions may be high for many, resulting in accusations that the course is more centered on gain than on authentic religious growth. That commercialization can be seen as exploiting the religious needs and vulnerabilities of an individual for financial gain.

Furthermore, the language and design of ACIM in many cases are criticized to be excessively complicated and esoteric. The course's heavy and repeated prose could be difficult to know and understand, leading to confusion and misinterpretation among readers. This complexity can produce a barrier to entry, which makes it problematic for individuals to fully interact with and benefit from the course. Some experts disagree that the convoluted language is a purposeful approach to hidden having less substantive material and to generate an dream of profundity. The issue in comprehending the product can also cause a dependence on external educators and interpreters, more perpetuating the commercialization and prospect of exploitation within the ACIM community.

Moreover, the notion of forgiveness as shown in ACIM has been criticized for being very simplistic and possibly dismissive of actual harm and injustice. The course advocates for a form of forgiveness that requires realizing the illusory nature of the observed offense and letting get of grievances. While this process can be helpful in selling inner peace and reducing personal enduring, it may not acceptably handle the complexities of certain circumstances, such as for instance abuse or endemic injustice. Experts disagree that this type of forgiveness is visible as reducing the activities of patients and absolving perpetrators of accountability. This will lead to an application of religious skipping, where persons use religious ideas to prevent coping with painful emotions and difficult realities.
