Not necessarily. It also depends on the level of deception. In other words, those who are incapable of being honest with themselves or have no clue how badly they've been deceived may have a better chance at salvation than those who intentionally ignore the truth. The bible points out that those who would believe a lie will be sent a "spirit of stupor". This may be a way for God to actually save those who are hopelessly lost.
That's a pretty big "If", and such a cavalier attitude towards one's eternal reward shows a significant lack of sincerity.
A few decades ago, there was a somewhat popular slogan to "Question Authority". Today society has come around to the more convenient view of "Trust the Science" which means trust that this is science, and that all scientists are infallible. The mindset is obviously no different than those who make these same claims with regards to their cultic leaders.
Society has come around to thinking like the Catholic church which then allows her to jump on top of that horse and lead the charge straight through the gates of hell.
