Why might institutions of authorithy tend to reject new ideas deveoped by scientist and other thinkers?

Institutions of authority may reject new ideas developed by scientists and other thinkers because these ideas challenge the status quo and may disrupt established power structures. The new ideas may also pose a threat to existing beliefs, practices, or policies that the institution upholds. Additionally, there may be a fear of change or loss of control associated with accepting and implementing these new ideas.
