Scotland have failed to win either of their opening two matches in the RBS 6 Nations and suffered a heavy 20-0 loss to England at Murrayfield last time out.
And while the Scots are yet to catch fire in this year's tournament, Johnson is not paying any attention to the criticism and is instead focusing on helping his side pick up their first win.
"I haven't given it a second thought to be honest. All I care about is the team - did we perform well? We didn't. Should we be disappointed? Yes we should," he said.
"It's amazing - the people that judge you the most know you the least. I am happy with who I am. I'm not changing. And I don't really care what they say about me.
"Everyone is entitled to their opinion; I'm not going to hold it against them. The people I care about are the people that are close to us."
The coach has recalled lock Richie Gray ahead of Saturday's clash with Italy.
Gray was told to improve his defensive work if he was going to win back his shirt and the second row has backed Johnson's decision to leave him out of the side.
He said: "It's been frustrating but I'm delighted to be back. It was disappointing to be left out because everyone wants to be involved. The first couple of days you bump your gums and say, 'Nah he's not right'.
"But Johnno was right. He wanted me to work defensively, work on the breakdown. You have to take those points on board and all you can do then is work on it.
"Hopefully I've done that and now I've got an opportunity to get back in the team."
