When it comes to expressing the sentiment that one's prediction or assumption has been confirmed, "I thought as much" is a commonly used phrase. However, there are other ways to convey the same message. One alternative is "I had a feeling," which suggests one's intuition guided their assumption. Another option is "I suspected as much," indicating that evidence or past experiences led to the prediction. "I anticipated it" conveys a sense of expectation or preparation, while "I was not surprised" suggests a lack of shock or disbelief. Regardless of the phrase chosen, the underlying message remains the same - one's initial thoughts have been validated.
