The Power of Belief: Why Credibility Wins Wars

Editor’s Note

In a conflict where perception is fast becoming as decisive as firepower, credibility has emerged as a weapon in its own right. The ongoing face-off involving Donald Trump, Israel and Iran has exposed a curious reality: claims, counterclaims, and narratives are no longer judged by their source alone, but by how events on the ground validate or contradict them. The sardonic refrain doing the rounds, that Trump’s statements are best “verified” by Iran, captures this erosion of trust with unsettling clarity. In a conflict shaped as much by narratives as by missiles, credibility is proving to be the true currency of power.

The author turns to the timeless canvas of the Mahabharata to make a strikingly contemporary point: wars are often decided not by the force of arms, but by the force of belief. It draws attention to the author’s central proposition, the ‘Credibility of Vector Theory’ (CoVT). In an age where information flows relentlessly, the decisive edge lies in who is believed. The piece makes a compelling case that in cognitive warfare, credibility is not incidental – it is decisive. It is built slowly, spent sparingly, and once eroded, rarely restored.

The Ashwathama Moment: A Lesson Beyond Deception

If ever words turned the tide of a war, it was in the episode of Dronacharya and his son Ashwathama. As Drona tore through the Pandava ranks, he seemed unstoppable. The only vulnerability identified in modern terms—a classic Centre of Gravity analysis—was his emotional attachment to his son.

What followed is often simplistically described as deception. On Krishna’s advice, Bhima killed an elephant named Ashwathama and declared, “Ashwathama is dead.” When Drona sought confirmation from Yudhishthira, renowned for his unwavering truthfulness, the reply came: “Ashwathama is dead… whether man or elephant, I do not know.”

The latter half went unheard. The effect was immediate. Drona, shattered, laid down his arms, leading to a decisive outcome.

But the real story lies deeper.

Beyond Deception: The Missing Variable

Deception in warfare is not new. What made this moment decisive was not the content of the message, but the credibility of the vector delivering it.

Had the same words been spoken by Arjuna, Bhima, or even Krishna, the outcome may well have been different. Drona did not act on information alone—he acted on trust. The message succeeded because it came from Yudhishthira, whose reputation functioned as a strategic asset.

It is the essence of what the author terms the Credibility of Vector Theory (CoVT).

Modern military thought increasingly recognises that wars are no longer fought solely in the physical domain. The cognitive domain, where perceptions, beliefs and decisions reside, has become the ultimate battlespace. Within this domain, however, a critical variable is often under-theorised: the credibility of the messenger or the vector. It argues that, in cognitive warfare, the efficacy of information is determined less by its content than by the perceived credibility of the vector delivering it.

At first glance, the Ashwathama episode is often interpreted as a classic example of deception. However, such a reading is incomplete. The deception itself is not novel; misinformation is as old as warfare. The decisive factor lies elsewhere. Hypothetically, let’s replace Yudhishthira with Arjun, Bheem or, for that matter, even Lord Krishna; would the prophetic words have had the same effect?

The answer would be a NO. The vector (person in this case) that delivered the effect had a reputation beyond doubt and was a deciding factor in the outcome. Drona’s decision was not based on the message alone, but on his trust in the messenger.

The point that clearly emerges when harnessing resources and effort towards cognitive domain dominance is that reputation management is a key enabler. While this may work at cross purposes from the oft-stated dictums of the cognitive domain; ‘first mover advantage”, “saturation of cognitive space”, “a lie repeated a thousand times becomes a truth”, however, the undisputable fact remains that the reputation of the vector is key.

In the present context of US-Israel v/s Iran conflict, the joke going around in social media is; President Trump’s statements are best verified by Iran.

Credibility of Vector Theory (CoVT) posits that the effectiveness of a cognitive operation is directly proportional to the perceived credibility of the vector delivering the information. The flow of activity for the action to outcome can be graphically explained as follows:

The key variables of vector credibility are:

Historical Integrity. Yudhishthira had never lied, and his reputation functioned as a strategic asset accumulated over time.

Neutrality Bias. Unlike Krishna, who is seen as a strategist and manipulator, Yudhishthira is perceived as morally anchored. Drona wanted to believe Yudhishthira, and this cognitive acceptance is influenced by emotional vulnerability.

The role of credibility as a force multiplier is deeply embedded in both classical and modern military thought. Napoleon underscored the primacy of “moral forces” in warfare, in which credibility is a critical subset that shapes belief and influences decision-making.

Similarly, Sun Tzu emphasised that “all warfare is based on deception.” Yet, deception is only effective when it is believable and believability, in turn, depends on the credibility of the vector.

Contemporary doctrines on cognitive warfare, including the one released in 2025 by HQ IDS, recognise the human mind as the principal battlespace and stress the importance of shaping perceptions rather than merely disseminating information.

However, a notable gap persists: while these frameworks focus extensively on narrative construction and engineering, they often under-emphasise the decisive role of who delivers the message, thereby overlooking credibility as a central determinant of cognitive success.
Credibility is inherently actor-specific and non-transferable, a reality that carries profound implications for warfare in the cognitive domain. It cannot be generated instantaneously; rather, it must be cultivated over time through consistent behaviour and perceived integrity, eventually functioning as a form of strategic reserve.

In the contemporary information environment, where data is abundant but trust is scarce, narratives succeed not necessarily because they are true, but because they are delivered by trusted or at least credible vectors. A false narrative amplified by a credible influencer can often outperform a truthful one originating from an untrusted source.

This dynamic is particularly evident in the contest between state and non-state actors. Non-state entities frequently succeed by building hyper-local credibility and leveraging identity-based trust networks, whereas state actors, despite their superior resources, often struggle with credibility deficits and perceptions of bias or propaganda.

At the leadership level, credibility directly influences public compliance, troop morale and strategic signalling; conversely, a leader perceived as unreliable risks undermining both deterrence and information campaigns.

The seeds of CoVT germinated after watching a series called ‘The Capture‘ streaming on JioHotstar. In the age of deepfakes and synthetic media, where verification becomes increasingly difficult and trust shifts from the content itself to the source delivering it. In such an environment, credibility emerges as the ultimate currency of influence. The manipulated surveillance footage in the series is accepted as truth not only because of its fidelity, but because it is validated by trusted institutional vectors and converts information into evidence. The series demonstrates that in a high-information, low-trust environment, the decisive factor is not the authenticity of content, but the authority of the entity presenting it. It reinforces the central proposition of CoVT; control over credible vectors enables control over perceived reality.

Accordingly, military strategy must reconceptualise credibility as a form of combat power, built in peacetime and decisively leveraged in conflict. Strategic communication must prioritise not merely the dissemination of messages, but the careful selection of credible messengers based on audience trust mapping. Ultimately, credibility management is a long-term endeavour; actions taken today shape the cognitive battlespace of tomorrow, and once lost, credibility is exceedingly difficult to restore, with cascading operational consequences.

The Ashwatthama episode is not merely a story of deception; it is a timeless demonstration of cognitive warfare executed with precision. Its enduring lesson is clear: Information does not win wars; belief does, and belief is shaped by trust in the source. In an era defined by information overload, psychological operations and contested narratives, the decisive advantage lies not in who speaks first or loudest, but in who is believed. Thus, credibility is not an adjunct to waarfare; it is a weapon system in its own right.
