Which of the following is a warning sign of radicalisation?

Isolation from colleagues serves as a significant warning sign of radicalisation due to its association with a withdrawal from social norms and supportive communities. When an individual begins to distance themselves from friends, family, and workmates, it can indicate a growing detachment from mainstream society. This isolation can provide fertile ground for extremist ideologies to take hold, as the individual may seek out alternative groups or narratives that reinforce their beliefs.

In contrast, increased social interactions and consistent performance at work generally reflect positive engagement with social and professional environments, which are counterindicative of radicalisation. Similarly, positive changes in behavior are often associated with personal growth or adaptation, rather than the negative connotations linked with radicalisation.
