The Buddies conceded a penalty early in the second half against Caley Thistle with David van Zanten punished for handball as he tried to block a shot at virtually point blank range from James Vincent.
Lennon refused to criticise referee Kevin Clancy for awarding the penalty, but felt that match officials are perhaps coming under too much scrutiny when it comes to making decisions, especially those that can change the outcome of a game.
He said: "I just feel that every time a decision is made that referees are under pressure from above. They want to stop the game and make decisions or make the big calls.
"You look at the one on the first have where the Inverness player (Gary Warren) got booked. It was the first real tackle in the game and he won the ball.
"You look at ourselves coming here and we're finding our feet having come back from pre-season.
"Officials have had the same respite as ourselves, so perhaps it will take them a bit of time to get back up to speed."
