  The broader adoption of social media platforms (e.g., TikTok), combined with
recent developments in Generative AI (GAI) technologies has had a
transformative effect on many peoples' ability to confidently assess the
veracity and meaning of information online. In this paper, building on recent
related work that surfaced the social ways that young people evaluate
information online, we explore the decision-making practices, challenges and
heuristics involved in young adults' assessments of information online. To do
so, we designed and conducted a novel digital diary study, followed by
data-informed interviews with young adults. Our findings uncover the
information practices of young adults including the social and emotional
motivations for ignoring, avoiding, and engaging with online information and
the ways this is entangled with collaborative arrangements with algorithms as
agents. In our discussion we bring these findings in close dialogue with work
on information sensibility and contribute rich insights into young peoples'
information sensibility practices embedded within social worlds. Finally, we
surface how such practices are attuned to prioritise wellbeing over convenience
or other commonly associated sufficing heuristics.
