Method of and system for fact checking email

1. A method programmed in a non-transitory memory of a device comprising:

a. automatically fact checking an email to determine a factual accuracy of the email by comparing, with the device, the email with source information, wherein fact checking occurs after the email is sent; and

b. automatically indicating a status of the email based on a result of the comparison of the email with the source information.

2. The method of claim 1 further comprising marking the email such that factually inaccurate statements are indicated.

3. The method of claim 1 wherein the email is indicated as spam if the email is factually inaccurate.

4. The method of claim 3 wherein the email is determined to be factually inaccurate if a number of factual inaccuracies in the email exceeds a threshold.

5. The method of claim 1 wherein the source information comprises a plurality of sources, and each source of the plurality of sources has a reliability rating based on the accuracy of information within each source of the plurality of sources, wherein the accuracy is determined based on previous fact checking results, wherein a first source with a first reliability rating is given more weight during fact checking than a second source with a second reliability rating lower than the first reliability rating, wherein each source of the plurality of sources with the reliability rating below a threshold is not used in fact checking.

6. The method of claim 1 wherein the source information comprises a plurality of sources, and each source of the plurality of sources has a reliability rating.

7. The method of claim 6 wherein the reliability rating is based on the accuracy of information within a source.

8. The method of claim 6 wherein a first source with a high reliability rating is given more weight during fact checking than a second source with a lower reliability rating.

9. The method of claim 6 wherein a source with the reliability rating below a reliability threshold is not used in fact checking.

10. The method of claim 9 wherein the reliability threshold is a user-specified threshold.

11. The method of claim 6 wherein the reliability rating is based on previous fact checking results.

12. The method of claim 6 wherein the reliability rating is determined by an impartial organization.

13. The method of claim 6 wherein the reliability rating is determined by users.

14. The method of claim 1 wherein fact checking includes analyzing causation within the email.

15. The method of claim 1 wherein the source information comprises user-selected sources for fact checking.

16. The method of claim 15 wherein sources of the source information are clustered to enable selecting of a cluster of sources to be used for fact checking.

17. The method of claim 1 wherein sources of the source information are selected based on characteristics of each source.

18. The method of claim 1 wherein fact checking occurs when the email is opened.

19. A method programmed in a non-transitory memory of a device comprising:

a. automatically receiving, with the device, a fact check result based on a comparison of email content with source information, wherein fact checking occurs after the email is sent; and

b. automatically providing the fact check result through an email system indicating the factual accuracy of the email content.

20. A device comprising:

a memory for storing an application for performing the following steps:

i. fact checking an email by comparing the email with source information, wherein fact checking begins based on a user input, further wherein fact checking occurs after the email is sent;

ii. indicating a status of the email based on a result of the comparison of the email with the source information; and

iii. marking the email such that factually inaccurate statements are indicated; and

b. a processor for processing the application.
