I have the following in my .emacs:

(add-hook 'latex-mode-hook #'outine-minor-mode)
(add-hook 'latex-mode-hook
      (lambda ()
          (outline-minor-mode 1)))

(I am aware this redundant, I am just trying to demonstrate that neither method works). Yet, when I open a *.tex file I see the following upon executing C-h m:

Enabled minor modes: Auto-Composition Auto-Compression Auto-Encryption         
Column-Number File-Name-Shadow Font-Lock Global-Font-Lock
Global-Hl-Line Global-Linum Line-Number Linum Mouse-Wheel Openwith   
Override-Global Tex-Pdf Tool-Bar Tooltip Transient-Mark

(Information about these minor modes follows the major mode info.)
LaTeX/P mode defined in `tex-site.el':
Major mode in AUCTeX for editing LaTeX files.
See info under AUCTeX for full documentation.

I understand from the above list of minor modes that the outline-minor-mode has not turned on. Why?

latex-mode-hook is the hook for the default Emacs latex mode. You appear to be using AUCTeX, which uses the hook LaTeX-mode-hook (note capitalization). More info in the AUCTeX manual.

You're using AUCTex. According to the documentation (section 5.1, use C-h i m auctex [RET] to read it in emacs), the hook name for AUCtex is actually LaTeX-mode-hook.

So just use instead

(add-hook 'LaTeX-mode-hook #'outline-minor-mode)

The hook latex-mode-hook also exists (see section 25.10.4 of emacs manual) but is used by emacs native tex/latex mode (when AUCTex is not loaded). This is arguably confusing.
