Winning consecutive sets VS grinding for third set

Hello all,

Watching the World Badminton Championship had me thinking that most of the matches went into decider third set. Singles / Doubles / Mixed.

Is it due to some strategic gameplan that is getting more popular among the coaches/players?

Is there some science behind it which predicts better outcomes for the person winning the first set?

Or simply that’s how long tournaments are played at professional level. Because as a casual player going into third set creates more panic/confusion o_O
