    A simple fact-checking capability that verifies if a given statement is supported by at least 3 facts.
    
    Each fact should be represented as a dictionary containing 'claim' and 'support' keys. 
    The claim is the statement to verify, and support is a boolean indicating its validity.

    >>> checker.add_facts([{'claim': 'Eden is an AI', 'support': True}, {'claim': 'AI can understand natural language.', 'support': False}])
    >>> checker.check('Eden is an AI')
    True
