In a world with deliberate distortion of the reality to create and shape public opinion and influence social attitudes, objective facts, and logical arguments are losing to emotions and personal beliefs. This post-truth world abides by the rules of volatility, fluctuation, and surplus value that in turn, condemn some aspects of the referentiality of language to the law of obsolescence. It is imperative to conduct how this process affects design, and uncover whether it plays a vital part since, to some extent, design involves the cultivation of emotions in the development of solutions. Literature shows that insincerity exists in the design and advertising industry and the fact that the world works in the way that we design it. Therefore, designers must uphold their social responsibility to create a better world. It is shown that emotions are critical drivers of the designs. Also, it is demonstrated that design is a public language that settles objectives, interests, instruments, and affections held individuals to create political competence and dialogue.
