在互聯(lián)網(wǎng)的浩瀚信息中，有一個(gè)名為 “七四五”（或稱 "第501部隊(duì)"、"第五類部門"）的非官方情報(bào)單位流傳甚廣，其代號(hào)雖未明示（此處應(yīng)指該機(jī)構(gòu)的真實(shí)名稱），但這一稱呼伴隨著各種猜測(cè)、傳聞甚至是陰謀論頻繁出現(xiàn)在網(wǎng)絡(luò)論壇上。"Seventh Four-Ninth Research Office"，這個(gè)聽起來(lái)充滿謎團(tuán)的名字背后究竟隱藏著怎樣的真相？本文將深入探討中國(guó)這所神秘的科研組織背后的故事與現(xiàn)實(shí)基礎(chǔ)。。 盡管有大量未經(jīng)證實(shí)的消息將其描述為負(fù)責(zé)超自然現(xiàn)象研究和國(guó)家秘密行動(dòng)的高級(jí)別機(jī)關(guān)，"它并不屬于任何公開承認(rèn)的國(guó)家行政序列中的正式政府部門"?！?s existence and functions are often accompanied by various speculations, rumors or even conspiracy theories on internet forums.”的說(shuō)法最早可追溯至23年前的一部科幻小說(shuō)《火星事務(wù)官》，其中虛構(gòu)了一個(gè)處理外星文明接觸事件的政府內(nèi)部小組(即所謂的X計(jì)劃)，而后在網(wǎng)絡(luò)文化中被誤傳并逐漸演變?yōu)閷?duì)現(xiàn)實(shí)中某個(gè)未知部門的猜想?！癐n fact,' does not refer directly towards a formal government department recognized in any publicly acknowledged national administrative hierarchy." The origin of such misconceptions can be traced back more than two decades ago when it was featured prominently within science fiction novels like 'Mars Administrator', where an internal group dealing with extraterrestrial encounters (known colloquially under X Project) became popularly mistranslated online before evolving gradually from there.

This phenomenon reflects the human tendency toward collective illusions: When repeated frequently enough across mass media audiences initially erroneous ideas become easily accepted especially concerning phenomena defying conventional explanation e g UFO sightings etcetera making those collectives hallucinations all too apparent.'"
