The Tigers arrived at Turf Moor in good spirits after wins over Derby and Norwich and a goalless draw with Nottingham Forest, but Pearson was forced to accept responsibility after his side slumped to a 4-0 defeat.
Pearson said: "We did the basics poorly. It's my team, so it's my responsibility and we'll be working hard to rectify things.
"It became a damage limitation exercise, but I still didn't think we showed enough discipline. I feel bitterly disappointed for the fans that travelled across.
"I'm sure they went home and thought 'what the hell have I seen there?' because it just wasn't good enough."
