Ludwig's WRAP-UP
In summary, "I have therefore" serves as a robust causal connector, effectively bridging premises and conclusions in formal communication. As confirmed by Ludwig AI, its primary function is to convey a reasoned decision or action. While highly valuable in professional and academic settings, it's advisable to use simpler alternatives in casual contexts. Remember that while phrases such as "consequently, I have" and "as a result, I have" can be used in its place, choosing the most fitting depends on the desired degree of formality and emphasis. The phrase's frequent appearance in reputable sources like The Guardian and The New York Times underscores its reliable usage in formal English.
