This study investigates the relationship between language and cognitive prejudices in decision-making procedures, mainly concentrating on the information framing effect within the framework of dual process theory in cognitive psychology. Through an incorporation of linguistic research and behavioral decision-making studies, it examines how linguistic determinants such as grammar, syntax, morphology, and semantics influence human cognition and lead to systematic biases. Drawing on diverse sources including computerized linguistic analyses, psychology experiments, and real-world language corpora, the essay elucidates four main factors: the relationship between language and cognition, the impact of linguistic framing, the role of linguistic ambiguity, and comparative studies on linguistic bias. The findings accentuate the important yet often ignored role of language in shaping decision outcomes and highpoint implications for individuals, corporations, and legal settings.
