H2 History Source-Based Questions: Modify the Hypothesis

Updated: Mar 12

Have you ever wondered how to modify the hypothesis in the H2 History SBQ part (b) assertion question? Look no further! This article is your ultimate guide, providing you with the essential know-how to effectively tweak and adapt your hypotheses.

In the context of H2 A-Level History, modifying the hypothesis refers to adjusting or refining the initial research question based on the evidence and analysis encountered during the course of investigation. This process allows H2 History students to develop a more nuanced and well-supported argument.

When modifying the hypothesis, there are several factors you should consider:

Tip 1 - Examination of evidence

As you conduct research and analyze the available sources and materials, you may encounter new information or perspectives that challenge or enhance your initial hypothesis. Pay attention to the details and interpretations presented in the sources and evaluate how they align with or deviate from your initial assumptions.

Tip 2 - Critical analysis

Critical Analysis: Engage in evaluation of the evidence. Assess the reliability, credibility, and bias of the sources you encounter. Look for patterns, connections, and gaps in the information that may prompt you to revise your hypothesis.

Tip 3 - Contextual understanding

Consider the broader historical context surrounding the topic or period you are studying. Evaluate the social, political, economic, and cultural factors that may have influenced events and individuals. This contextual understanding can help you refine your hypothesis to reflect a more comprehensive and accurate analysis.

Tip 4 - Integration of new perspectives

Be open to exploring different interpretations and perspectives on the topic. Consult a variety of sources and scholarly works to gain a deeper understanding of the historical discourse surrounding your subject. Incorporate these new perspectives into your analysis and use them to refine your hypothesis.

Example of Scenario of Modifying Hypothesis

Let me provide you with a possible scenario that you may encounter while delving into Cold War case studies.

Initial Hypothesis: The Cold War was primarily driven by ideological differences between the United States and the Soviet Union.

As you conduct research and analyse the evidence, you may come across new perspectives and information that challenge or complicate the initial hypothesis. Let's say you encounter evidence suggesting that geopolitical and strategic considerations played a significant role in shaping the Cold War.

In light of this evidence, you might want to modify your hypothesis as follows:

Modified Hypothesis: The Cold War was driven by a complex interplay of ideological differences, geopolitical considerations, and power struggles between the United States and the Soviet Union.

In this modified hypothesis, you acknowledge that while ideological differences were indeed a significant factor, other factors such as geopolitical considerations and power struggles also contributed to the development and escalation of the Cold War. By incorporating new evidence and perspectives, your hypothesis becomes more nuanced and reflective of a comprehensive understanding of the topic.

Throughout your answer, you would have analysed the sources, and the sources would have supported your modified hypothesis much more than the original hypothesis. The sources would have explored how geopolitical considerations, such as the desire for global influence and the pursuit of strategic advantages, influenced the actions and policies of both the United States and the Soviet Union. Additionally, they would have underlined the ways in which power struggles, such as the arms race and proxy wars, shaped the dynamics of the Cold War.

Remember, modifying the hypothesis should be based on a careful evaluation of the evidence and a critical analysis of different perspectives. It's important to maintain coherence and logical progression in your argument while incorporating new insights that enhance your understanding of the Cold War.


All in all, this is how you would go about modifying the hypothesis in the H2 History case study component. By examining evidence, engaging in critical analysis, understanding the context, and incorporating new perspectives, you can change the given hypothesis.
