I've seen friendly dolphins at least once before. This roughly just means that I both die and drink from fountains a lot.
And I didn't ever got a stat increase from sci-talk in my life IIRC. Tried it with banana growers before, but got so bloody bored I resigned any further attempts - maybe I was just doing it wrong.
Banana growers won't help much. The best way to boost your Int & Wis at an early stage is simply, reading scrolls, books, and praying and offering. This will usually get you to about 20 for each. Only then is it worth science talking. Once you get to 20 Int/10 Wis, talk to the librarian. You'll see the boost immediately.
