Common mistakes

"well-grounded" and "well-founded" mean exactly the same thing
"well-grounded" emphasises the connection to a base (evidence, experience, or psychological stability); "well-founded" emphasises the quality of the foundation itself

"Well-grounded" and "well-founded" overlap significantly but have distinct emphases. "Well-grounded" tends to emphasise the connection to something real — the grounding in evidence, experience, or practice. "Well-founded" tends to emphasise the quality and strength of the foundation — how well-built the basis is. A claim can be well-founded on a single compelling piece of evidence; a position is well-grounded when it has been developed through sustained contact with the relevant reality.

"well-grounded" = stable and calm (only psychological meaning)
"well-grounded" has both an intellectual meaning (based in evidence or experience) and a psychological meaning (stable and secure in one's identity)

In modern usage "well-grounded" is used in both intellectual contexts (a well-grounded argument, a well-grounded theory) and psychological or spiritual contexts (a well-grounded person, a well-grounded response to difficulty). The two uses share the same core metaphor of secure contact with what is real and solid.

A trick to remember it

well-grounded = "firmly grounded" (ground = solid earth, base). Picture a person or idea literally standing on solid ground, not floating in the air.
