The phrase "Why won't the new supply believe the old supply?" appears to be ambiguous and lacks context, making it difficult to provide a specific answer. However, I can offer a few possible interpretations:
Change in Information: In certain contexts, the "new supply" might not believe the "old supply" due to a difference in the information presented. Information might have evolved or changed over time, leading to discrepancies between the old and new supply. This could be a result of updates, advancements, or revisions in knowledge, data, or evidence.
Lack of Trust: The "new supply" might not trust the "old supply" for various reasons. This could be due to prior experiences, doubts about the credibility of the old supply, or a perception of biases, inaccuracies, or vested interests in the information provided by the old supply.
Generational Gap or Perspective: Sometimes, there can be a generational gap or difference in perspectives between the old and new supply. The new supply might have been exposed to different ideas, values, or ways of thinking that conflict with the beliefs or information held by the old supply.
Competition or Conflict: In some cases, there could be competition or conflict between the old and new supply. This could lead to a lack of trust or willingness to accept information from each other.
Differing Interpretations: The old and new supply might have different interpretations or analyses of the same information, leading to disagreements and a lack of belief.
Lack of Evidence or Proof: The new supply might be demanding more substantial evidence or proof from the old supply to support their claims, and until that is provided, they may remain skeptical.
Remember, without a specific context, it's challenging to pinpoint the exact reason why the new supply won't believe the old supply. Different situations can have varying dynamics and reasons behind such skepticism or disbelief. If you can provide more context or clarify the scenario, I'd be happy to help with a more tailored response.
