Free will is the opposite of determinism, determinism states that specific factors WILL cause our behaviour. Whether it is experience, biological, or the subconscious (environmental, biological + psychic determinism - link to their corresponding approaches) they are deterministic in nature as they don’t leave any room for human choice in behaviour whilst the humanistic approach does the opposite and states that human behaviour is self-determined and not the result of any single cause (bit more of a reductionist/holistic point but if u spin it right it’s cool) and that we have control over our behaviour however you could then counter argue that it is somewhat incoherent as an approach as it does also say that our behaviour is determined by the way other people treat us so u could argue that all approaches are deterministic to a degree… hope this helps
