At the first stages, all the participants in Guilford’s original study censored their own thinking by limiting the possible solutions to those within the imaginary square (even those who eventually solved the puzzle).
Therefore, part of the challenge lies in either allocating your praise equally among all characters, or (more likely) figuring out whose good side is worth getting on and whose isn't.
The results of having a good or bad relationship value are varied.
Common examples include unlocking an alternate cutscene, gaining access to a different ending, or simple gameplay buffs/bonuses.
Guilford was one of the first academic researchers who dared to conduct a study of creativity.
He challenged research subjects to connect all nine dots using just four straight lines without lifting their pencils from the page.
