While most evidence helps strengthen a speech, it can be an invaluable source of information. Facts such as statistics or opinions of other people are beneficial, sometimes speakers use personal experience to manipulate their speech. Many speakers can make up these experiences in order to persuade their listeners that his or her speech is the most correct. While this can appeal to pathos, an emotional technique, their store could be made up for the sole purpose of winning over their audience. However we cannot 100% know that these stories are true. Most stories are exaggerated to make them more interesting, so when telling a personal experience, back it up with statistics and evidence.
