Perception Filters working on Time Lords

Its noted in the article that Perception Filters do not work on time lords, and cites "The Sound of Drums" as the source, but after just reviewing a few key scenes from the episode, it appears that it does work on them. The Master doesn't acknowledge the Doctor until he makes a run for the Master, and as mentioned earlier in the episode, running, sudden moves, or drawing attention to yourself will break the effect. Is there any other points to cite showing that perception filters don't work on Time Lords?

Addendum: Ok, the Master does say 'As if a perception filter is going to work on me.' That could mean that he is intelligent enough that it won't work, OR it doesn't work on Time Lords, however the question still stands, is there any other evidence that it doesn't work on Time Lords in general? -- Kooky 04:44, 12 February 2009 (UTC)

Its either the Filet works on TL's or it doesnt. If it does, then only the intelligent TL's can see it, its only because the Master is one of them he could, as he says "As if a perception filter is going to work on ME", emphesis on me. If not, then its fine either way :DOoiue 21:19, May 8, 2010 (UTC)

I assumed the Master meant he was too intelligent to be fooled. I mean, the Doctor and the Master are both Time Lords, if it has never worked on the Doctor due to biological reasons, then why would he bother using it against another Time Lord. Makes no sense. I'm going to remove the line. If someone has a citation for the inclusion of the bit of info, please add it. Vegnas 12:11, May 15, 2010 (UTC)

Torchwood 3

Does anyone find it a glaring error in Torchwood when Jack first show's Gwen the lift? The Doctor said, and as cited in this article, that drawing attention to yourself renders Perception Filters useless but Jack shows Gwen the Torchwood lift and it's perception filter effects by shouting at passers by and going unnoticed.Lyco 23:04, May 19, 2010 (UTC)

Not particularly, no. First, the perception filter isn't on them, it's on the lift. And second, the thing it's filtering is the retraction of the curb/pavement and the actual operation of the lift. When the lift has been returned to the "up" position, there's nothing to "filter" anymore. It's just a part of the normal curb/pavement, then. What's more glaring to me is the rather broad application of the perception filter. It was a lovely, elegant concept in The Sound of Drums and even The Eleventh Hour, but I didn't understand its usage at all in Vampires of Venice. As I understood it before that episode, it was merely supposed to make something "unnoticed", which is a cool concept. But it Vampires, it acts as a disguise, which is a significantly different concept. CzechOut ☎ | ✍ 05:23, May 20, 2010 (UTC)
