The fourth step to finding the most impactful philanthropic causes is to seek expert advice from people who have more knowledge and experience in the field. Experts can provide you with valuable insights, recommendations, and feedback that can inform and improve your giving decisions. You can find expert advice from a variety of sources, such as charity evaluators, philanthropy advisors, and peer networks. Charity evaluators rate and review different charities based on their impact, transparency, accountability, and cost-effectiveness. Examples include GiveWell, Charity Navigator, and ImpactMatters. Philanthropy advisors are professionals who offer personalized guidance and support to donors based on their goals, interests, and budget. Examples include Giving Compass, Rockefeller Philanthropy Advisors, and The Philanthropy Workshop. Peer networks are groups of like-minded donors who share their learnings, experiences, and best practices with each other. Examples include Giving Pledge, Effective Altruism Community, and Philanthropy Together.
