This paper examines disinformation through a Peircean semiotic perspective, arguing that it is not the opposite of information but rather an ethical distortion of it. By situating disinformation within an ecosystem shaped by digital platforms, algorithms, and datafication, the study highlights how it reinforces pre-existing beliefs and constrains the expansion of knowledge. Drawing on Charles S. Peirce’s concepts of information, semiosis, and interpretants, the authors propose that disinformation operates through pragmatic purposes that differ from those of information: while information seeks continuous, self-correcting knowledge, disinformation sustains belief rigidity by exploiting emotional, energetic, and logical interpretants. The analysis explores how disinformation mobilizes adherence, sharing, and activism, forming habits of action resistant to contrary evidence. Ultimately, the paper characterizes disinformation as a semiotic process of ethical deviation that maintains ignorance and fosters dissent, thus shaping social behavior within contemporary communication environments.
