Context is important.

Initially, The World newspaper and others mistakenly reported that the Titanic's passengers were all saved due to miscommunicated wireless messages. Later, their headlines reflected the tragic reality, like "NO HOPE NOW OF OTHER TITANIC SURVIVORS" on April 16, 1912.
Initial Misinformation

Cause:
Confusion over wireless telegraph messages led to a belief that the Titanic's passengers were safe. A positive response about another ship in distress was mistakenly applied to the Titanic.
Newspaper Coverage:
Some newspapers published headlines like "Titanic sinking no lives lost" and "all saved from the Titanic".

Correction and Realization

Correction:
The news cycle quickly shifted as the true scale of the disaster became clear. By April 16, 1912, The World headline shifted to acknowledge the loss of life.
