People who lack sufficient information on a given subject—or who do not think about it much—may arrive at a number of mistaken ideas, or may be deliberately led astray by others.
For example, for those with little interest in how a television works and no idea of what components the mechanism consists, the television set is simply a means of watching films or news programs. Those people will be unable to appreciate the marvelous technology in the apparatus if they remain unaware of how the video and audio signals reach the television, and do not consider how the image appears on the screen.
