My blunder checks don't work

Hi all, I am a 1600 FIDE rated player and I make blunders from time to time in slow games.
What really bugs me is that blunder checks never seem to work for me. I know I am supposed to stop before a move and ask myself whether I am making a blunder, and I am aware of the technique of watching the position with a "fresh eye".
However, it never works for me, and I always spot the refutation the exact moment I play my move, as regular as clockwork.

What can I do to improve my blunder checks?

Move confirmation + take more time.

How does 1600 FIDE translate to lichess ratings?

Why have you resigned this one?

@Hitsugaya around 1850-1900

Switch on move confirmation in your profile. Think about your move, play it, check it is no blunder, confirm.

Ask yourself what you are leaving behind when you make a move

@eskimoform @tpr it helps...

@itzkyda don't bother watching my games. The latest ones were played blindfolded and this account is basically inactive.
@Hitsugaya probably anywhere from 1700 to 2100, personally I'm around 1950 in rapid.
@tpr Thanks, I didn't know about that option, although I'm looking for a solution in otb play.

@odoaker2015 Thanks for the video links!

In the second video we have 4. Keep track of your opponent's plans and 5. Anti-blunder check. While Smirnov recommends making #4 the first thing in the move selection process, I did not hear him say how to "trigger" doing #5. A time tested technique is to sit on your hands! Removing your hand to make the move can be the trigger to do the anti-blunder check.
The anti-blunder check is often referred to as "Blumenfeld's Rule" (see for example "Chess Tactics for the Tournament Player" by Palatnik and Alburt).

@JEth9921 If you are already making the blunder check, but having it fail right after you make the move, perhaps the advice from the above book might work . They say to write down the move (or pretend you are doing it if not allowed). Try to put yourself in the frame of mind that you are getting into when you do see the blunder. Is that frame of mind triggered by something else? Is that when you really look at what your opponent is going to do?
