The Gorgie outfit shipped seven goals to holders Celtic as they were knocked out of the William Hill Scottish Cup.
That excruciating drubbing followed punitive punishments dished out to the administration-hit Jambos, which mean Gary Locke is banned from signing new players, leaving him to work with a squad whose average age is just 22.
But defender Wilson - who will lead the side out against Scottish Premiership rivals United at Tannadice - insists their display against the Hoops has not left them worried about future beatings.
He said: "We can't go in fearing another result like that. If you do then there is no point turning up.
"The most important thing is that we learn from it. We have seen the mistakes we have made - now we need to eradicate them from our performances.
"But we don't go into any game fearing a hammering. We go in hoping to win. It was the same on Sunday but it didn't happen. Now we just need to move on."
The Tynecastle men will finally return to zero points with a win on Tayside - six months after they were fined 15 points for breaking insolvency rules.
Before turning his attention to Jackie McNamara's side, though, Hearts manager Gary Locke forced his squad to sit through a re-run of Sunday's defeat.
While it was uncomfortable viewing, former Liverpool centre-half Wilson insists it was educational.
He said: "We can't erase last weeks game from our minds. As bad as it was and as embarrassing as it was, you have to try and learn from every experience.
"We came in on Monday and went through the game, trying to see where we could have done better. Celtic may have been exceptional but we were nowhere near where we should have been.
"Was there a fear coming in on Monday to watch it again? Yeah, there probably was because we had lived through it once. We didn't want to do it again.
"We sat there and discussed it. Some people aired their views but the video footage didn't lie and it was clear we were lacking in a lot of places.
"But I think the young lads will be fine. They have played the majority of the season and have performed well. Hopefully we can just put that down as a bad day at the office."
Locke admitted his young side may end up bruised by the heavy burden placed on them this season and the situation they face is much bleaker than the positive atmosphere at United that has allowed their own youngsters to blossom.
Teenagers like Ryan Gauld and Andrew Robertson have impressed in recent weeks, but Wilson said they do not have the same weight of responsibility to carry as the Hearts recruits.
"We have seen how well Dundee United are doing," he said. "They have got a lot of good young players that are all coming through at the same time.
"They are performing really well but they are in a different situation to us. They have different pressures on them.
"Our boys are doing well to and hopefully on Saturday they continue to do as well as they have been."
