情報源として欠かせないが、信頼はできない。

\nインターネットが情報源として欠かせないと多くの10代〜40代が答えているが、信頼している人はそれに比べとても少ない。
\nそもそもインターネットを信頼できる人はとても少ないようだ。
\n一方新聞は、購読率が低い層（10代〜30代）は新聞への信頼度は高いとは言えないが、購読率が高い60代以降はまずまずの信頼度である。
\nテレビについては、NHKテレビが新聞と同じくらいの信頼度を得ているが、民放テレビの信頼度は高いとは言えない。
\n
\nまた10代〜30代若い世代の信頼度は、どの情報源も信頼度が50％に満たっていない。インターネットよりも、新聞など他の情報源の方が「信用できる」答えている人が多いにも関わらず、「情報源として欠かせない」の割合ではインターネットが圧勝している。\n「情報源として欠かせないか」と「信頼できるかどうか」は比例しないらしい。\n

\n新聞を読む人は年々減っている。
\nちなみに私は今日も読んでいない。明日になって読むかは分からない。今後も読むかは分からない。
\n「新聞を読みなさい。」とまた言われるのだろう。
\n
\nなぜ人々の新聞離れは止まらないのか？
\n理由は様々だが、大きな理由の一つとして他の情報メディアの存在が挙げられるだろう。\n

\n世の中には新聞以外にも様々な情報メディアがあり、私たちにたくさんの情報をくれる。
\nそのたくさんの情報の中でどの情報が真実で、それが嘘かなど見分けるのは難しい。
\nだからこそ信頼できることがいいこととも、信頼できないことが悪いこととも言えない。
\nしかし多くの若い世代が信頼できる情報を得られていない、得た情報を信用できていない現状があるようだ。
\nたくさんの情報源の中で、どれが信頼できるかできないか見極めるためには、もしかしたらどれか一つの情報源に偏ったりせず、どの情報も自分の目でしっかり確認することが重要で、その一つとして新聞を読むことも必要であるのかもしれない。\n
