Finding the psychological edge ahead of a big fight can be akin to striking gold and Carl Frampton's camp clearly believe they are a point up going into tonight's showdown with Scott Quigg.
The build-up to previous major fights have often provided evidence of such an impact, most notably when Steve Collins spooked Chris Eubank with his use of a psychologist ahead of their first fight, which the Dubliner subsequently won on points.
This week Quigg and his coach Joe Gallagher have been riled by the row over the dressing room, on the back of the dispute over who the officials should be for the biggest fight both men have ever been in.
That Frampton is the bigger box office attraction is surely indisputable, despite the claims of Team Quigg. The Jackal is expected to have the majority of the support among 19,000 fans in the Manchester Arena while in the social media world he happens to have 156,000 followers compared to Quigg's 91,000 - Frampton's latest single tweet enjoying 1,600 likes and almost a 1,000 retweets.
Tonight he aims to live up to his billing as the main attraction and the IBF champion's team are certain that WBA champion Quigg has started to become a little unnerved by the row over the dressing room and the magnitude of the occasion.
Frampton's coach Shane McGuigan even fears for how Quigg will react when he suffers his first defeat on the biggest stage he has been on, having given so much to the sport since he was 15 years of age.
"Quigg's a winner, his whole life is in this. He eats and sleeps boxing - the problem with that is when the the harsh reality of defeat comes crashing down on him," said McGuigan.
"He's going to become a sad and very unfulfilled man once he doesn't win and I'm going to feel sorry for him."
