The Critiques of Adult Development Stage Theories, Fairly Stated
The main objections to stage theories of adult development, stated in the critics’ terms, with what the evidence still supports
Are stage theories of adult development scientific?
It depends on the theory and on the claim. Some stage measures have a long validation record with known limits, and critics have pressed on scoring, on the samples behind stage descriptions, on sex and culture bias, and on whether one newer model was publicized as validated before its research report was available. In the 2017 exchange over STAGES, the critique raised ten points by the 2020 count of Tom Murray, who co-authored the 2020 research summary with O’Fallon (the response itself refers to eleven issues), one of them that the model was prematurely promoted as validated. The developers accepted that timing point, and by Murray’s 2020 account said nine of the ten rested on misconceptions. On this page’s reading, the reviewers’ own conclusions are more qualified than either “proven” or “nonsense,” and the page states each objection in its author’s terms.
Are stage theories of adult development scientific? The answer depends on which theory and which claim. Some measures have a long record of testing; others, on this page’s reading of the sources, rest mainly on studies by their developers. The critics do not object to the same thing. Some question how stages are scored. Some question whether the people in a stage study can stand in for everyone else. Some question whether a model was described as validated before its research was public. This page states those objections in the terms their authors used, reports what the reviewers themselves concluded the evidence still supports, and turns the objections into guardrails for reading a stage claim.
Three bodies of work carry most of the debate. Lawrence Kohlberg’s stages describe moral reasoning, from reasons based on punishment and self-interest up to reasons based on universal principles. Jane Loevinger’s stages describe ego development, the frame of reference through which a person organizes their sense of themselves and the world; she measured it with the Washington University Sentence Completion Test (WUSCT), in which a person finishes 36 open sentence beginnings and raters score the endings against a scoring manual. The STAGES model, developed by Terri O’Fallon, is a newer framework that builds on the work of Loevinger and of Susanne Cook-Greuter, a researcher in the same tradition.
A stage label is easy to hear as a fact. On this page’s reading, a stage description is a hypothesis about how people reason, and how far that hypothesis reaches depends on who was studied, how their answers were scored, and who checked the scoring. The practices below are checks drawn from those objections. None of them can place you or anyone else at a stage, and none has been tested as an intervention.
Pratiche
- Close the reading and come back to the room
Put the stage reading down, feel your feet and breath, and let the shame loosen before you decide anything about where you stand.
- Reach a person if the shame is more than a reading can carry
If the shame about where you stand starts to feel like not wanting to be here, reach a trusted person and a clinician now.
- Check who validated a stage model before you repeat its claims
When a stage model is described as scientifically proven, find out who ran the validation, whether the report is public, and whether anyone outside its developers has checked it.
- Prefer a scored assessment to reading yourself into a stage
Do not pick the stage description that sounds most like you; if you want a level, use a scored instrument, and treat your own sense of your stage as a guess to test.
- Do not place someone at a stage from one conversation or one moment
Before you judge where a colleague, partner or child sits in a stage model, collect more than one sample and keep what you observed separate from the label you are tempted to attach.
- Check whether the people in a stage study resemble the people you are describing
Before you apply a stage description to people in another culture, class or community, find out who the original samples were and what they had in common.
- Read a gender gap against the schooling and jobs of the people measured
When a study reports that men or women score higher on a developmental measure, check whether education and occupation explain the gap before you conclude anything about sex.
- Ask whether a moral scoring scheme counts care and emotion as reasons
When a framework ranks how mature a person’s moral reasons are, check whether reasons grounded in relationships, feeling and loyalty were scored at all.
- Hold a critique next to the support the reviewers still found
When you read a critique of a stage theory, also write down what the reviewers concluded the evidence still supports, and keep both halves of the verdict in view.
- Check whether a stage claim’s evidence came from children or from adults
Before you apply a stage claim to adult life, find out how old the people were in the studies that produced it, and whether those studies tested adults at all.
Come si collegano queste pratiche
Every practice on this page works from one question that the critiques of stage theories share: what evidence stands behind a claim about where a person, or a group, sits on a developmental sequence, and how far does that evidence reach? The practices check who did the validating, whether the people studied resemble the people being described, whether a scoring scheme counted the reasons a person actually gives, and whether a critic’s own conclusion keeps the model standing. None of them decides whether the stages are real. They keep a stage claim no wider than the evidence beneath it.
How well supported is Loevinger’s sentence completion test of ego development?
Loevinger (1979) reported internal consistency of about .85 and called the construct-validity evidence substantial, but said it falls short of clear proof that the stages form a fixed sequence. She judged the test adequate for research when it is administered and scored with sufficient care, and not for diagnosing an individual without other data. Manners and Durkin (2001) reviewed the construct, predictive and discriminant validity of the theory and the test, and their abstract concludes there is substantial empirical support for its conceptual soundness.
Do Kohlberg’s moral stages hold across cultures and between men and women?
The answer depends on which part of the claim. Snarey (1985) reviewed 45 cross-cultural studies and reports striking support for the underlying assumptions behind Kohlberg’s claim of universal moral development, and also major caveats about the range and general applicability of the stages and biases in favor of complex urban and middle-class populations. On sex differences, Walker (1984) found only a few inconsistent differences in childhood and adolescence, and reported that adult studies confounded sex with education and occupation. Jaffee and Hyde (2000) found small average differences in moral orientation and said their findings do not offer strong support for the claim that care is used mainly by women and justice mainly by men.
Has the STAGES model been validated, and who checked the validation?
Its validation claims have been disputed in print, and the developers have partly conceded the point. In a 2017 exchange, a critique by Cook-Greuter, Wilber and Sharma raised ten points, by Murray’s 2020 account, one of which was that the model was prematurely promoted as validated. The developers’ response said it did not agree that validity was misrepresented, but accepted that it was promoted prematurely, because the statistical report was not yet available for colleagues to scrutinize. By Murray’s account the response said nine of the ten points rested on misconceptions (the response itself counts eleven), and it also names a business rivalry running in both directions. The same response says STAGES research “is in its infancy, with just a tiny amount of empirical validation compared with Loevinger’s WUSCT.” The 2020 validation study’s first author is the model’s developer, and in 2023 Merckoll argued that the two studies cited as validating STAGES scoring do not hold up under scrutiny.
Can a stage score tell me who I am?
Not on its own, by the measures’ own cautions. Loevinger (1979) judged the sentence completion test not suitable for individual diagnosis without other data. In the STAGES research, Murray and O’Fallon (2020) report retest data from 115 clients: of 143 retests, 38% stayed the same, 50% rose and 11% fell. The authors note that many of the test-takers had been in a program that taught developmental models, and that they may have learned vocabulary that led to higher verbal-textual scores (scores on the written wording of the answers) without advancing deeper development. The authors read the 89% who stayed the same or rose as strong evidence for a developmental construct, while noting that the 11% who fell could reflect rater error, test-retest variability or real regression under stress. The practices here treat a score as one reading to be discussed, not as a label.
Do the studies of moral stages in children prove the stages apply to adults?
Those studies were of children, and they describe children more directly than adults. Walker (1980) assessed fourth- to seventh-grade children and found transitions to stage 3 reasoning only among children who had the hypothesized prerequisites. Blatt and Kohlberg (1975) gave children in schools twelve hours of moral discussion over twelve weeks, and the experimental group tended toward higher moral thinking than controls. A reader who wants to apply a stage claim to adult life can ask which ages and settings the evidence came from.
Come scegliere tra queste?
If a stage model has been described to you as proven, start with who validated it and whether the report is public. If you are trying to place yourself or someone else, prefer a scored instrument to a self-chosen description, and collect more than one observation before you place anyone. If you are applying a description across culture, class or sex, ask who the original sample was and what else differed between the groups. If you are reading a critique, read the support clause next to the objection. If the stage claim comes from research on children, treat it as a claim about children until you have evidence from adults.
Cosa questi approcci non risolvono
This page is a reading of the critiques, and it does not rule on whether any stage model is scientific. Loevinger’s measure has a long record, but she herself said the evidence falls short of clear proof of sequence. On this page’s reading, much of the support cited for these models is correlational and drawn from particular samples. The newer STAGES validation was publicized before its research report was available, by the developers’ own account, the developers say the research is in its infancy, and the first author of the 2020 validation study is the model’s developer. The 2023 critique concerns scoring rather than the theory. Snarey and Walker reviewed older literature, and the Gilligan argument is reported through secondary sources because her book was not read for this page. None of the eight practices has been tested as a way to change anyone’s stage.
