Albion head to Leicester City in their next game on Monday knowing a 10th defeat in a row away from home would equal a single-season club record stretching back nearly 100 years.
Although Mason has called the losing run “a bit embarrassing”, seven of the nine defeats have been by a one-goal margin.
“We should’ve come out on top in quite a few of them, and that’s the difference,” he said.
“Football’s a game of such small margins. As players and coach you have to take responsibility.
“We are creating and putting ourselves in positions but you’ve got to be able to take the chances and for some reason we aren’t and there are many different reasons for that.
“But we’re not a million miles away. Sometimes you need a bit of brilliance, need a bit of quality, a bit of luck, sometimes when you’re on a run it doesn’t always go your way.”
Mason added that he is “not going to ask the fans for patience” and says they are right to feel unhappy with current results.
“We’ve lost too many games. I’m unhappy and it hurts me,” he added.
