Is Blitz Generally Harder to Beat than Rapid and Standard Games?

I've found it incredibly hard to move up in blitz and that the play is often just as good if not much better at the lower ratings.  

I play 5 and 10 minute blitz (rarely bullet and 3 min.).   And I also play rapid/standard (15 min.+) games.  

The players with higher ratings in rapid and standard (1200-1400) make really big mistakes that are often unprovoked and simplistic (just randomly hanging a piece), while people playing 900 through 1100 blitz seem equal or better.  

Is this normal?  

(On a side note:  Does anyone think low-rated players cheat at all here?)

.. All the evidence, suggests .. that's 'Normal'; Since regardless, of how 'high' one's rating may be ; Remember that, {with few, private 'side-bet' exceptions} ; No, $$ are  at stake ; And, as for, the collective, anonymous Egos, re. any 'rating-point' decline; Those 'points' are easily recovered ; If, they decide to give a 'blitz' game, the attention, it deserves ..

.. Plus, I'd imagine ; Most are playing .. to escape, something More pressing, on their minds ; Which can be, a distraction, in itself !

.. As for, the 'fishes' playing 'tougher' than you'd imagine !? .. It could be, a combination, of 3rd party, assistance ; Plus, {no offense} ; You Not seeing, a succession, of inaccurate moves, {by either, or both players} ; In a faster, time- frame.  o:

Thx for the thoughts, Flank.  

Although, I'm not sure I understand your logic in some of those comments.  lol.  

I just find it weird that people playing 1200-1400 rapid/standard on Chess.com are easier to play against than 900-1100 blitz players.  

Contrary to that. it is harder to win at standard time control. At standard time control you need to be more accurate and have more patience. Things that you can get away with blitz, won't work at standard time control against good opponents.
