We use the bounded-confidence model, with fixed uncertainties and extremists, for investigating how the population’s opinion is resilient to the arrival of a new group. The resilience of the population only depends on the equivalent energy of the group arrival, this latter being called tipping energy. The higher the uncertainty of the moderate agents, the higher the resilience of their moderate mean opinion to the arrival of a new group. The single extreme cluster emerges in the case of a null tipping energy.
