命运探知

Reading Steiner，全称命运探知之魔眼(運命探知の魔眼)The Reading Steiner is a term referring to Rintaro Okabe's ability to, after switching world lines, retain his memory of events that have occurred (from his point of view) before the switch.

世界线变动时，原世界线的记忆会被自动覆盖消失。

此时海马体一定会在侧头叶上构筑新的记忆情报

但就像是硬盘删除数据无法删的不留痕迹一样，

用专业软件的话有时基至可以恢复

世界自动的因果修复程序也会直接干涉人的记忆

既是说，即便世界线改变了，人的记忆也被重构了

但实际上人之前的记忆情报并未完全在新可能性世界上消失，而仅仅是被删了

删掉与消失的概念略微不同，因为会留下删除的痕迹

甚至人脑也如电脑一样，在直接删除时，原先的资料其实还存在于大脑无法读取到的地方，人可通过外界的刺激，“复原” 一些这样的记忆

冈部的RS本质是无法写入新记忆，由于新世界和旧世界之间的差别而头疼。

如果存在世界线变动并不影响到网部视点上的历史的前后关系（比如遥远的赛博坦星球的人造出了时间机器改变了宇宙的另一边，那么冈部也不会RS）

In 1.382733β, this ability is referred to as President's Disease, as those with this ability remember Puchin as the President of Russia instead of General Secretary of the Soviet Union.

Deja Vu is one of the main factors for Reading Steiner as it was stated in the anime that the Deja Vu and reading Steiner are highly related.

World lines can be switched by altering the past, for example through the use of D-mails.

While no other members of the cast have this immediate knowledge of a switch having occurred or any recollection of what happened in another World Line, they seem to regain fragments of these memories occasionally.

Faris remembers sending the D-Mail that prevented her father's death after escaping the Viral Attackers with Okabe in 0.409431α. Lukako remembers her first meeting with Okabe as a male in 0.456914α. Mayuri, visiting her grandmother's grave in 0.571046α, remembers "Nightmares" in which she dies in a multitude of ways. Katsumi Nakase gains this ability during November 2010 in 1.129848β. Yuki pretends to have Reading Steiner to help her hide it in 1.382733β. Kurisu remembers some of her Alpha worldline memories in the Steins Gate worldline. The ability plays a major role in the plot, most prominently in allowing Rintarou to undo the changes caused by the D-Mails and not losing track after each switch.

In the anime, there is a visual distortion every time a Reading is activated, usually following the sending of a D-mail.

The movie Steins;Gate: Fuka Ryouiki no Deja Vu features the Reading Steiner as an important plot element, as Kurisu and Mayuri use recollection of the pre-Steins Gate world lines to piece together information about Rintarou. The movie Steins;Gate: Fuka Ryouiki no Deja Vu confirms that the Deja vu is a part of the Reading Steiner ability
