Final answer:
Dunbar's number suggests a limit of 150 stable social relationships one can maintain, and while social media allows for more connections, the core idea remains significant.
Step-by-step explanation:
The question pertains to determining whether Dunbar's number applies to social networks when social media is considered.
When social media is added to Robin Dunbar's formula, it is indeed false that Dunbar's number does not apply. Dunbar's number suggests that humans can only maintain a stable social relationship with a certain number of people, which is around 150.
However, social media platforms potentially allow for a larger number of connections, so the applicability of Dunbar's number to modern online social networks can be debated. Nevertheless, the core idea behind Dunbar's number, which relates to meaningful social connections, still holds significance despite the influence of social media.
