Yet, traditional aggregation methods fail to capture individual judgments since they rely on the notion of a single ground truth. Our aim is to review prior contributions to pinpoint the shortcomings that might cause stereotypical content generation. As a preliminary study, our purpose is to investigate state-of-the-art approaches, primarily focusing on the following two research directions. First, we investigate how adding subjectivity aspects to LLMs might guarantee diversity. We then look into the alignment between humans and LLMs and discuss how to measure it. Considering existing gaps, our review explores possible methods to mitigate the perpetuation of biases targeting specific communities. However, we recognize the potential risk of disseminating sensitive information due to the utilization of socio-demographic data in the training process. These considerations underscore the inclusion of diverse perspectives while taking into account the critical importance of implementing robust safeguards to protect individuals' privacy and prevent the inadvertent propagation of sensitive information.1 aMuscato, Benedetta1 aMala, Chandana, Sree1 aManerba, Marta, Marchiori1 aGezici, Gizem1 aGiannotti, Fosca1 aAbercrombie, Gavin1 aBasile, Valerio1 aBernadi, Davide1 aDudy, Shiran1 aFrenda, Simona1 aHavens, Lucy1 aTonelli, Sara  uhttps://aclanthology.org/2024.nlperspectives-1.5/
