A response to the Theory of Dyadic Morality
The Theory of Dyadic Morality (Schein and Gray, 2017) is a theory of moral psychology / judgement / cognition. It states that things that are intentionally harmful are seen as immoral, and crucially, that things that are immoral are seen as harmful. There is hard data to back up this assertion:

This shows that perceptions of harm and perceptions of immorality, of a particular topic, match up closely.
The definition of harm is extended from harm to the person, to harm to other things like society or abstract principles.
The Theory of Dyadic Morality (TDM) thereby rests on the "dyadic" causal relationship
between harm and immorality. It predicts that: 1) perceived harm (and therefore
perceived immorality) are on a continuum of severity, instead of being "all or nothing";
and 2) harm and immorality form a self-
This mutual reinforcement may be related to the "Smoke Detector Principle" (Nesse, 2004). This states that we pay much more attention to potential threats than to potential opportunities, for good evolutionary reasons: it is better to give a false alarm than to be dead or injured. Potential harm is a threat.
Over the course of human history, there has been a general trend towards greater
general compassion and social justice (Pinker, 2011). Human morality seems to be

An alternative, complementary explanation for this phenomenon is increased sympathy for suffering victims because of the removal of restrictive norms. If someone breaks a moral norm, we tend to disapprove of them, and disapproving of someone leads us to have less sympathy for their pain (Decety, 2011). We literally feel someone's pain less, if we disapprove of them or their actions. Over time, sexual norms have become relaxed, leaving norms of compassion and justice intact, and if no norm has been broken, no disapproval is warranted, and we may then have emotional resonance with the pain of previously persecuted groups such as gay people.
Dill and Darwall (2014:22) describe a number of times throughout history when public social disapproval of unethical behaviour made it more expedient to behave ethically rather than unethically.
This historical drift towards greater compassion and social justice is consistent
with the self-
The case for moral dumbfounding
TDM appears to be an excellent and realistic theory of moral psychology. The one place it falls down in my opinion is its treatment of moral dumbfounding, and this gap is a result of the theory of moral psychology not having an adequate theory of morality to respond to.
Moral dumbfounding is where you ask someone why they think something is immoral, and they cannot tell you. Famously, Immanuel Kant said that he knew that masturbation was wrong, but he didn't know why. Jonathan Haidt (2013) and other researchers have presented subjects with a number of "harmless" wrongs and asked them to say what was wrong about them: such as consensual incest between adult siblings; having sex with a roast chicken and then eating it; or smearing faeces on a Bible. Typically, people were unable to say exactly what was wrong with these things. TDM maintains that this was because they were "not allowed" to say they were harmful. In contrast, experiments by Schein and Gray (2017) have shown that people define the immorality of these things in terms of harm.
However, the explanations in terms of harm are unconvincing.
For example, Anita Bryant believed that the “purity” violation of gay rights would convince kids to be gay, which would not only destroy their vulnerable immortal souls but also undermine procreation and hence the American family, which would bankrupt the nation and eventually lead to anarchy (Bryant, 1977).
Anita Bryant (1977) -
Anita Bryant is a Christian, and religious people are well known for their opposition
to homosexuality in itself, never mind for other reasons. Religious people disapprove
of gayness full stop. But if you ask them why, they are not able to come up with
convincing reasons. Ultimately they are likely to point to the male-

We may observe that the morality of groups/teams/partnerships is parallel to the morality of families. The goal of each is the inclusive fitness of individuals, and altruism is in proportion to the value the recipient can bring to the donor (whether utility value, or genetic value). In a group, the Stakeholder Principle dictates that "I will help you when the benefit I gain from your well being is greater than the cost I incur in helping you." In a family, Hamilton's Rule states that "I will help you to the extent that we share genes" (Perry, 2021:48).
Harmless harms
So, in some cases of immorality, what is being harmed is sacred values. If a value is either something we value in itself (i.e., a goal), or a policy for achieving a goal, then it is possible to damage it through the "wrong" behaviour.
Legitimate harm
