* One of the most recent and peculiar instances of [[The Coconut Effect]] is the addition of [[Lens Flare]] to [[Post Processing Video Effects|computer-generated scenes]]. [[Lens Flare]] is a ''flaw'' resulting from the physical properties of the camera lens, but it is so ingrained in the public consciousness that its absence makes a scene look "fake;" it may be that adding it adds to the audience's [[Willing Suspension of Disbelief]], by implying that the scene was actually shot by a camera (perhaps via the [[Literary Agent Hypothesis]]).

** ''[[Firefly]]'' deliberately took this concept to the logical extreme: the CGI space scenes not only included [[Lens Flare]], but also moments where the camera takes a second to find or focus on an object, or where a speeding spacecraft is blurry and slightly out of frame. The new ''[[Battlestar Galactica]]'' makes similar use of a faux camera for many space scenes; in one episode, the camera is even struck and knocked spinning by debris from an explosion. Joss Whedon points out in his commentary that brand new, state-of-the-art lenses had too ''little'' lens flare for him, so they switched them out for cheaper ones that would have wider lens flares.

** It's not even limited to anime - there has been at least a few [[Manga]] out there where the artist has ''drawn'' a lens flare when a character is, say, looking into the sun. People just seem to expect to see flares.

** Not only that, lens flare occasionally crops up even in ''1st person computer games'', where it has no justification whatsoever. This was especially prevalent after the introduction of affordable 3D accelerator chips in the 90's, when games began featuring ridiculously overexaggerated, colorful lens flare en masse due to that could be rendered it without a noticable drop in performance. Thankfully the excitement of the new had given way to better taste and subtler visuals in recent years.

* The stroboscopic effect often seen on spoked wheels, fans, helicopter blades, etc. is another example of a camera artifact which is so expected by audiences that it's left in, even though there ''are'' cameras and shutter mechanisms available which would eliminate it. Although there are situations where stroboscopic effects are visible to the naked eye, commonly observered under street lights (50 or 60 hertz flicker), and sometimes even in broad daylight (PNAS article [http://www.pnas.org/content/93/8/3693.abstract here]).

** When using the defibrillator, the defibs must always charge with an audible, high pitch sound. And the defib paddles are always rubbed against one-another when charging. When discharged, the defibs also make a loud SHUNK. Let's not forget that the person using them always says "CLEAR!!"<br /><br />"Clear!" is sort of [[Truth in Television]]. However, in reality, the users will say, "Clear the patient," and then check to see if all persons are no longer touching the patient. A single dramatic "Clear!" followed by no safety check and a zap is pure Hollywood.

** In addition to this, a defibrillator is unable to revive a "flatlining" (asystolic) patient, which runs contrary to their depiction in medical dramas. The heart's electrical system controls the muscles of the heart. A defibrillator is designed to "reset" the heart's own electrical system when it's erratic and causing the muscles to contract wildly (fibrillation, as in ''defibrillator''). If the muscles of the heart are no longer responding to the electrical system (for example, Pulseless Electrical Activity), or if the electrical system is down (asystole), there's nothing to be gained by shocking the patient.

* [[Man in a Kilt|Kilts]] in Scotland. The pleated kilt as we know it today was invented in the 18th century; prior to that there was the greatkilt, which was essentially a big blanket (which may or may not have been tartan) wrapped round the waist and pinned at the shoulder. This probably dates from the 16th century. It was ''illegal'' for Highlanders to wear a kilt between 1746 and 1782 - it was seen as a rebel military uniform. And modern "Highland dress" was invented in the lowlands in the 19th century. The upshot of all this is that Scotsmen in kilts in nearly ''every'' historical period tend to be wrong, unless it's [[The Present Day]] and they're at a wedding.
