抄録

現代のデジタル情報環境において、エコーチェンバー効果は民主的議論と批判的思考を阻害する深刻な問題となっている。本稿では、この問題に対処するための理論的・実践的枠組みとして、Quatro Dynamic Thinking（QDT）モデルを提案する(Tanaka 2025a, 2025b)。QDTモデルは、深さ（ダイビング思考）、広さ（エクスパンディング思考）、関係性（ネットワーキング思考）、時間性（フローイング思考）という四つの思考次元を統合することで、認知的閉鎖性を克服し、多様な視点への開放性を促進する。本稿では、各思考次元がエコーチェンバー効果の異なる側面にどのように作用するかを理論的に検討する。
