Yet another position of review is having less scientific help for the statements created by ACIM. The course asserts that its teachings may lead to profound religious transformation and therapeutic, but these claims are not supported by scientific research or scientific studies. Without scientific evidence to right back up their assertions, ACIM depends greatly on anecdotal evidence and personal recommendations, which are inherently subjective and unreliable. Having less rigorous, goal research makes it difficult to determine the real effectiveness of the program and increases issues about its overall legitimacy.

The professional facets of ACIM also invite skepticism. Since its publication, the class has spawned a multi-million money market which includes acim  books, workshops, seminars, and on the web courses. Authorities argue that the commercialization of ACIM undermines its religious concept and raises honest considerations in regards to the motivations of people who promote it. The large expenses related to participating in ACIM-related activities may be high for several, resulting in accusations that the class is more dedicated to profit than on real spiritual growth. This commercialization is visible as exploiting the religious wants and vulnerabilities of individuals for financial gain.

Moreover, the language and design of ACIM in many cases are criticized to be very complicated and esoteric. The course's thick and repetitive prose could be complicated to understand and interpret, ultimately causing distress and misinterpretation among readers. This complexity can make a barrier to entry, making it burdensome for individuals to totally engage with and benefit from the course. Some critics argue that the convoluted language is really a deliberate method to obscure the lack of substantive material and to produce an impression of profundity. The issue in comprehending the substance may also result in a dependence on additional teachers and interpreters, further perpetuating the commercialization and possibility of exploitation within the ACIM community.

Also, the notion of forgiveness as presented in ACIM has been criticized to be very simplistic and possibly dismissive of true hurt and injustice. The class advocates for a questionnaire of forgiveness that requires recognizing the illusory nature of the perceived offense and making get of grievances. While this process could be valuable in selling inner peace and reducing particular enduring, it could maybe not adequately address the difficulties of particular situations, such as for instance abuse or endemic injustice. Critics disagree that this type of forgiveness is seen as reducing the experiences of victims and absolving perpetrators of accountability. This will cause a questionnaire of spiritual skipping, wherever persons use religious methods to prevent dealing with uncomfortable emotions and difficult realities.
