Recognizing the Warning Signs: What Every Parent and Professional Should Know About Radicalization

When a loved one begins to change in troubling or confusing ways, it can be hard to know what’s normal — and what might be something more serious. For parents, educators, counselors, and other frontline professionals, understanding the early warning signs of radicalization is crucial for preventing violence and supporting vulnerable individuals before it's too late.

The National Counterterrorism Center (NCTC), in partnership with the FBI and DHS, has released a valuable public resource: the Mobilization Indicators Booklet (2021)

This guide outlines behavioral indicators that may signal someone is moving toward violent extremist activity.

What Is “Mobilization”?

Mobilization is the process by which someone moves from holding radical beliefs to actively planning or committing violence. While beliefs alone aren’t crimes, actions based on those beliefs can endanger lives — including the life of the individual themselves.

Recognizing behavioral indicators early can make it possible to intervene before violence occurs.

Key Warning Signs to Look For

Some of the most urgent indicators highlighted by the NCTC include:

• Preparing for violence: Acquiring weapons, making tactical plans, or researching methods of attack.

• Justifying harm: Using ideological or religious arguments to support violence.

• Seeking training or travel to conflict zones or extremist destinations.

• Expressing intent to harm specific people, groups, or institutions.

• Sudden isolation from family, community, or long-held beliefs — sometimes replaced by online extremist networks.

One sign alone doesn’t mean someone is radicalizing. But multiple, escalating behaviors — especially involving violence or ideology — deserve careful attention.
