The psychological influence of ACIM on its adherents is another part of concern. Whilst the course claims internal peace and religious enlightenment, some mental health specialists have increased alerts about its possible to trigger confusion, disillusionment, and also emotional harm. The course's emphasis on the illusory character of the product earth and the ego may cause persons to problem the truth of these experiences and feelings in methods may not be beneficial. For a few, that questioning may result in a decreased volume to cope with real-world problems and associations, ultimately causing solitude and a feeling of detachment from life. Authorities argue that such an method can be particularly harmful for persons who are previously susceptible or experiencing emotional health issues.

Still another place of critique is having less empirical help for the statements made by ACIM. The class asserts that its teachings can cause profound spiritual transformation and healing, but these claims aren't supported by medical study or  acim clinical studies. Without empirical evidence to straight back up their assertions, ACIM depends seriously on historical evidence and personal testimonials, which are inherently subjective and unreliable. Having less demanding, target study helps it be hard to confirm the true efficiency of the class and increases issues about their overall legitimacy.

The industrial aspects of ACIM also invite skepticism. Because its book, the course has spawned a multi-million dollar business which includes publications, workshops, seminars, and on the web courses. Critics argue that the commercialization of ACIM undermines their religious concept and increases moral considerations in regards to the motivations of those that promote it. The high expenses related to participating in ACIM-related actions may be prohibitive for all, leading to accusations that the class is more centered on gain than on true religious growth. That commercialization is visible as exploiting the religious wants and vulnerabilities of individuals for economic gain.

Moreover, the language and framework of ACIM tend to be criticized for being very complicated and esoteric. The course's thick and repeated prose may be demanding to know and read, ultimately causing distress and misinterpretation among readers. This complexity can cause a barrier to access, rendering it difficult for people to completely engage with and take advantage of the course. Some authorities argue that the complicated language is really a purposeful approach to obscure the possible lack of substantive material and to generate an impression of profundity. The difficulty in comprehending the product can also result in a dependence on additional teachers and interpreters, further perpetuating the commercialization and potential for exploitation within the ACIM community.
