Groups tend to be pessimist to change and outside influence though so aren't inherently biased to optimism. Groups just value optimism when it is optimism towards the groups current values and goals, but it sees optimism towards stuff the group doesn't do as a negative. For example, if you join a company and tell the manager in the first meeting "If we reorganized the working groups like this it will greatly increase productivity due to reasons, it will be great!", he wont see you as an optimist, even though you have plenty of optimism, what he wants is optimism towards his ideas and not your own optimistic ideas.
