If the humans can TARDIS-proof a room, then why can't the obviously more intelligent species such as the Daleks, Cybermen and others TARDIS-proof their ships?

We have no idea! It's a new thing.

Like deadlock seals and "the sonic doesn't do wood," every now and then a writer or producer decides that the Doctor's technology needs to be limited. Sometimes it's done well, and sometimes it's done thoughtlessly.

In this case, the idea of TARDIS-proofing a room was necessary for a cool entrance effect, and it doesn't seem much thought was given to its implications. We haven't heard of this thing before, and that's why none of the Doctor's enemies have ever done it.

That said, the vast majority of the Doctor's adventures have not featured the TARDIS except as a way to show up. TARDIS-proofing your Evil Gravel Quarry of Doomsday Plotting would just mean the Doctor has to park a little further away and walk.

" park a little further away and walk." I'm sure he'd RUN (or take a scooter). Bells of St. John IMO had one of the better reasons not just to appear there, although I guess that wouldn't have fit in The Day of the Doctor. – Mario Jan 5 '14 at 14:23
Maybe the other races just lack the necessary "human stupidity." – Amy Jan 5 '14 at 16:17

Clutching at straws, but it could also be that TARDIS proofing a ship could also affect the performance.

If, for example, you built something that stopped a TARDIS from getting in through time it could, on a Dalek ship, stop them from using time corridors.

That’s a very good point actually. It’d be like making an aeroplane entirely out of the material they use for the black box. It’d be absolutely indestructible, and utterly incapable of flight. – Paul D. Waite Jan 5 '14 at 14:51
This is my theory. The line about “human stupidity” makes me think there’s a potentially harmful side-effect. – alexwlchan Feb 2 '14 at 16:57

The Daleks and Cybermen have spent countless years attempting tardis-proofing, using all manner of exotic physics and wibbly-wobbly, timey-wimey stuff.

UNIT just lowered their ceilings.

lowered their ceilings ?? – Adeetya Jan 5 '14 at 13:17
Actually an interesting thought: What happens if they just make the whole room so small that there's never enough room for the TARDIS to materialize. It's able to materialize and then contain something, but so far that's always been a human (or alien) or something else that's pretty small. – Mario Jan 5 '14 at 14:24
There'd probably be a way around that. There was a first-Doctor story (which I've never seen) where everyone was shrunk to a very small size. I'm not certain, but I think the Tardis was shrunk as well. – luser droog Jan 5 '14 at 20:00
And another first Doctor story where a TARDIS was shrunk and its pilot could no longer get inside, so I guess dimensionality is another wibbly-wobbly thing. (The Time Meddler) – Patrick Hughes Jan 5 '14 at 22:28
It would probably just land sideways without warning, because that's how the TARDIS rolls (poorly). – Liesmith Dec 3 '14 at 18:13

Maybe its because UNIT have studied the TARDIS in first hand, like when the 3º Doctor was stuck in the Earth. Maybe its because the room is in a temporal distorsion, like in the Angels Take Manhattan. UNIT find that temporal distorsion and said, "Let's make a Doctor-proof room for our nasty secrets!" or something like that. This may not be first time that UNIT try to take some restrains into the Doctor, like the Arton Sensors that figured in the 7 Season.
